Question:

Julio reads that apples contain an average of 6 seeds. He thinks the number of seeds is greater for Granny Smith apples. He randomly samples 20 Granny Smith apples and calculates a sample mean of 6.3

Julio reads that apples contain an average of 6 seeds. He thinks the number of seeds is greater for Granny Smith apples. He randomly samples 20 Granny Smith apples and calculates a sample mean of 6.3 seeds with a standard deviation of 1.42 seeds. Conduct a significance test for the mean with a significance level of α = 0.10 and make a conclusion.
○ -0.945 > -2.093; Julio rejects the null hypothesis. The test suggests that Granny Smith apples have a greater mean number of seeds.
○ -0.945 > -1.328; Julio rejects the null hypothesis. The test suggests that Granny Smith apples have a greater mean number of seeds.
○ 0.945 < 2.093 ; Julio fails to reject the null hypothesis. The test suggests that Granny Smith apples have an average of 6 seeds.
○ 0.945 < 1.328; Julio fails to reject the null hypothesis. The test suggests that Granny Smith apples have an average of 6 seeds.
