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.
