Excel computes a two‑sample confidence interval for the difference in proportions just as well and as easily as Minitab and othe
True [87]

Answer:

See ecplanation below

Step-by-step explanation:

False.

On the Data analysis tool from excel we can conduct the following procedures:

Anova: Single Factor

Anova: Two factor with replication

Anova: Two factor without replication

Correlation

Covariance

Descriptive statistics

Exponential smoothing

F-test Two sample for Variances

Fourier analysis

Histogram

Moving Average

Random number generation

Rank and percentile

Regression

Sampling

t test: Paired two sample for means

t tes: Two sample assuming equal variances

t test: Two sample Assuming Unequal Variances

z test: Two sample for means

And as we can see we don't have an specific procedure just to obtain confidence interval for the difference of proportions. We need to remember that if we select a z test in excel, for example the output will contain the confidence associated to the parameter, but for this case is not too easy obtain a confidence interval for the difference of proportion like on a statistical software as (Minitab, R, SAS, etc) since all of these statistical softwares are elaborated in order to conduct all the possible statistical tests and confidence intervals for parameters of interest.

The average fuel efficiency of U.S. light vehicles for 2005 was 21 mpg. If the standard deviation of the population was 2.9 and
statuscvo [17]

Answer:

1) The probability that the mean mpg for a random sample of 25 light vehicles is 0.042341.

2) between 20 and 25 --> 21-25/2.9 = -1.38

Step-by-step explanation:

Problem #1:

  • Using the z-score formula, z = (x-μ)/σ/n, where x is the raw score = 20 mpg,μ is the population mean = 21 mpg , σ is the population standard deviation = 2.9, n = random number of samples.
<h3><u>X < 20</u></h3>
  • = z = 20 - 21/2.9/√25
  • = z = -1/2.9/5
  • = z = -1.72414
<h2><u><em>Now</em></u></h2>

<em>P-value from Z-Table:</em>

<h3><u>P(x<20) = 0.042341</u></h3>

Problem #2:

<h3>21-25/2.9 = -1.38</h3>

Artist 52 [7]

Answer:

-117

Step-by-step explanation:

So, basically all you have to do is use the absolute values in order to use order of operations and simplify it along with the multiplied grouping.

Hope this helps :)

A number is doubled and then increased by three the result is 71 what is the original number
musickatia [10]
34 is the original number.  
This is because 34 times 2 is 68 and 68 plus 3 is 71.
