A banana company claims that the mean weight of their banana is 150 grams with a standard deviation of 18 grams. Data generated from a sample of 50 bananas randomly selected indicated a mean weight of 153.5 grams per banana. Is there sufficient evidence to reject the company's claim? Use a = 0.05. Given: Reject Ho if z < -1.96 or z > 1.96 The graph will be a bell shaped and shaded at both tails at [ left side at z = -1.96 and right side at z = 1.96] z = (x -μ)/[o /√n] z = (153.5-150)/[18/√50] Z = 1.375 We fail to reject the null hypothesis because 1.375 < 1.96 There is not sufficient evidence to support the rejection of the company's claim. To Do: Kindly draw what the given stated (draw the rejection region).

Question
A banana company claims that the mean weight of their banana is 150 grams with a standard deviation of 18 grams. Data generated from a sample of 50 bananas randomly selected indicated a mean weight of 153.5 grams per banana. Is there sufficient evidence to reject the company's claim? Use a = 0.05.
Given:
Reject Ho if z < -1.96 or z > 1.96
The graph will be a bell shaped and shaded at both tails at [ left side at z = -1.96 and right side at z = 1.96]
z = (x -μ)/[o /√n]
z = (153.5-150)/[18/√50]
Z = 1.375
We fail to reject the null hypothesis because 1.375 < 1.96
There is not sufficient evidence to support the rejection of the company's claim.
To Do: Kindly draw what the given stated (draw the rejection region).
