A national survey conducted in 2011 among a simple random sample of 1,507 adults shows that 56% of americans think the civil war

kifflom [539]

Answer:

Null : x = 0.56 ; Alternate : x < 0.56

t = (x - 0.56) / (s / √n) : If < tabulated t at α =0.05 , null hypothesis accepted

If t > tabulated t at α =0.05 , alternate hypothesis is accepted

Explanation:

Hypothesis Testing is used to test the statistical validity of a statement. Null Hypothesis is the neutral hypothesis, signifying equality to the tested value. Alternate Hypothesis is the contradictory hypothesis, signifying deviation from the tested value.

To test 'Proportion of people giving importance to civil rights in american political life' : Let these proportion be = x

<u>Null</u> Hypothesis (H0) : x = 56% = 0.56

<u>Alternate </u>Hypothesis (H1) : x < 56 % , i.e x < 0.56

't' statistic is calculated based on sample : ( x' - u ) / (s / √n)

where : x' = sample mean , u = population hypothesised mean = 0.56 , s = sample standard deviation , n = sample size

If this calculated 't' < tabulated 't' at significance level α =0.05 ; null hypothesis is accepted. It implies average people thinking as mentioned = 56 % (majority)

If this calculated 't' > tabulated 't' at significance level α =0.05 ; alternate hypothesis is accepted. It implies average people thinking as mentioned < 56% (not majority)

A Quality Analyst wants to construct a sample mean chart for controlling a packaging process. He knows from past experience that

AlexFokin [52]

Answer:

There are 5 questions altogether, so the answers and explanations are below.

Explanation:

QUESTION 1

Whenever the packaging process is under control, package weight is normally distributed with mean of 20 ounces and standard deviation of 2 ounces. This makes the true mean lie between 18 and 22 [subtract 2 from 20 and add 2 to 20].

For Monday, the mean is the addition of the values then divided by 4. That is, 92/4 = 23

For Tuesday, same computation follows. We have 84/4 = 21

For Wednesday, 80/4 = 20

For Thursday, 76/4 = 19

For Friday, 80/4 = 20

For the packaging process to be out of control, the mean weight for that day of the week must be outside the interval.

The answer is option (A) Monday because the mean weight for that day exceeds the upper limit of 22 ounces.

QUESTION 2

Accordingly, he sampled 4 units of output from each machine.

We will find the mean of the output units from each machine.

M1 : (17+15+15+17) ÷ 4 = 64/4 = 16

M2 : 84 ÷ 4 = 21

M3 : 92 ÷ 4 = 23

The correct answer is option (A) Machine Number 1 because the process mean for that machine is outside the control limit specified. The value 16 is below the lower limit value of 16.71.

QUESTION 3

It is the same as question 2 BUT we are to find the estimate of the process mean for whenever it is under control.

The interval given [16.71 - 23.29] represents the interval within which the process means for machines which are 'under-control' will fall. Hence the estimate of the process mean for whenever the machines are under control is:

(23.29 + 16.71) ÷ 2 = 40/2 = 20

The correct option is (C) 20

QUESTION 4

Specification requires that the piece of material be between 52.47 and 55.53 inches.

The process that produces the piece of material yields an interval of [53.1 - 54.9].

This is gotten from the subtraction of the standard deviation/error from the process mean of 54 and adding the standard error to the process mean of 54.

The answer is option (E) None of the above. This is because the correct answer is 100%. All pieces produced by the process fall within 53.1 and 54.9 inches and this interval falls rightly within the required specification of [52.47 - 55.53] inches.

QUESTION 5

Here, process mean interval is same as the required interval. Subtracting the standard deviation from the process mean and adding it to the process mean, we get our lower limit and upper limit respectively. The distribution of output is also normal.

Since the process is under/in control, it means that the 5 samples had sample means that are within the required interval.

So, since distribution of output (mean) is Normal, 85.01% of the sample means will fall within the middle values of 85.01% of the interval.

The interval spans 1.6 points or inches. This is the distance or difference between the upper and lower limits.

85.01% of 1.6 is 1.36016

We will divide this interval into two so we can get our new standard deviation and subtract it from 59, as well as add it to 59, to get the new interval within which 85.01% of sample means will fall.

1.36016 ÷ 2 = 0.68008

So the new lower limit is 58.31992

New upper limit = 59.68008

Correct answer is Option (E) None of the above

85.01% of sample means will fall within [58.31992 - 59.68008]

If approximated to 3 decimal places as in the options given above, 85.01% of sample means will fall within [58.320 - 59.680] inches.

GOOD LUCK!!

If overapplied or underapplied overhead is material, it should be disposed of by allocating it to: Select one: a. Cost of goods

noname [10]

If overapplied or underapplied overhead is material, it should be disposed of by allocating it to Cost of goods sold and finished goods inventory.

Option A

Explanation:

Fixed Overhead expenses are allotted to on the basis of predetermined overhead rate to each unit. Sometimes overhead expenses estimated and actually incurred have differences.

If the actual overhead is more than overhead applied to production than it is called under applied overhead. When actual overhead is less than applied overhead than it is called over applied overhead.

Balance of difference of these overhead is debited or credited to Cost of goods sold of company.
