Given the sample mean = 22.75, sample standard deviation = 3.6638, 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 0.1 significance level. a) Identify the correct alternative hypothesis:

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