Question

Given the sample mean = 22.175, sample standard deviation = 4.6403, and N = 40 for the low income group,

Test the claim that the mean nickel diameter drawn by children in the low income group is greater than 21.21 mm. Test at the 0.05 significance level.

a) Identify the correct alternative hypothesis:

μ>21.21μ>21.21
μ=21.21μ=21.21
p=21.21p=21.21
p>21.21p>21.21
μ<21.21μ<21.21
p<21.21p<21.21

Give all answers correct to 3 decimal places.

b) The test statistic value is:

c) Using the Traditional method, the critical value is:

d) Based on this, we
