18. Consider the following hypothesis test.

The following results are for two independent samples taken from the two populations.

1. What is the value of the test statistic (round to 2 decimals)?

2. What is the p-value (round to 4 decimals)? Use z-value rounded to 2 decimal places.

3. With  = .05, what is your hypothesis testing conclusion? (Reject or Accept)

4. p-value is

a. >= to 0.05

b. > 0.05

c. <= 0.05

d. < 0.05

e. = 0.05

f. not equal to 0.05

Sample 1	Sample 2
n1= 40	n 2= 50
x1= 25.4	x2= 22.4
1= 5.1	2= 7

18. Consider the following hypothesis test. H0: Sigma 2= 7 1. What is the value of the test statistic (round to 2 decimals)? 2. What is the p-value (round to 4 decimals)? Use z-value rounded to 2 decimal places. 3. With = .05, what is your hypothesis testing conclusion? (Reject or Accept) 4. p-value is a. >= to 0.05 b. > 0.05 c.

Solution

1)

z=2.35

2) p value is 0.0094

3) Reject.

4) d
