(20 points) A statistics practitioner calculated the mean and the standard deviation from a sample of 400. They are x = 98 and s
Nimfa-mama [501]

Answer:

The P-value is 0.0234.

Step-by-step explanation:

We are given that a statistics practitioner calculated the mean and the standard deviation from a sample of 400. They are x = 98 and s = 20.

Let = population mean.

So, Null Hypothesis, : = 100 {means that the population mean is equal to 100}

Alternate Hypothesis, : > 100 {means that the population mean is more than 100}

The test statistics that will be used here is One-sample t-test statistics because we're yet to know about the population standard deviation;

T.S. = ~

where, = sample mean = 98

s = sample standard deviation = 20

n = sample size = 400

So, the test statistics = ~

= -2

The value of t-test statistics is -2.

Now, the P-value of the test statistics is given by;

P( < -2) = 0.0234 {using the t-table}

Which polynomial function has zeros at 2, −4, and 1?
LuckyWell [14K]

Answer:

y = (x - 2)(x + 4)(x - 1)

Step-by-step explanation:

Given the zeros of a function say x = a and x = b, then

The factors are (x - a) and (x - b) and

y = (x - a)(x - b)

Given the zeros are x = 2, x = - 4, x = 1, then

the factors are (x - 2), (x - (- 4)) and (x - 1), that is

(x - 2), (x + 4), (x - 1) , thus

y = (x - 2)(x + 4)(x - 1)

What is the mean absolute deviation of the data set? {12, 10, 10, 8, 6, 7, 7, 12}
Simora [160]

Answer:

The MAD of  {12, 10, 10, 8, 6, 7, 7, 12} is 2.

Step-by-step explanation:

<u><em>Step 1 : Add all the values Up:</em></u>

<u><em /></u>12+10+10+8+6+7+7+12=72

<u><em>Step 2 : Divide them by the number of items or numbers:</em></u>

<u><em></em></u>\frac{12+10+10+8+6+7+7+12}{8}=9<u><em></em></u>

<u><em></em></u>

<u><em>Step 3: Find the absolute deviations:</em></u>

<u><em></em></u>12-9=3\\10-9=1\\10-9=1\\9-8=1\\9-6=3\\9-7=2\\9-7=2\\12-9=3\\<u><em></em></u>

<u><em>Step 4: Add all the absolute deviations:</em></u>

3+1+1+1+3+2+2+3=16

<u><em>Step 5: Find the mean:</em></u>

\frac{3+1+1+1+3+2+2+3}{8}=2
