A power company is installing utility poles that are supposed to have a height of 40 feet. The foreman checks a random sample of 60 poles to determine if the mean height is 40 feet at a significance level of 0.05. From the histogram, can normality be assumed?( YES or NO?) x= t= p= Since the p-value is ____ (GREATER or LESS)than the significance level 0.05, the null hypothesis ___(FAILS TO BE REJECTED or IS REJECTED). (SUFFICIENT or INSUFFICIENT ) evidence exists that the mean height differs from 40 feet.

A power company is installing utility poles that are supposed to have a height of 40 feet. The foreman checks a random sample of 60 poles to determine if the mean height is 40 feet at a significance level of 0.05.
From the histogram, can normality be assumed?( YES or NO?)
x=
t=
p=
Since the p-value is ____ (GREATER or LESS)than the significance level 0.05, the null hypothesis ___(FAILS TO BE REJECTED or IS REJECTED). (SUFFICIENT or INSUFFICIENT ) evidence exists that the mean height differs from 40 feet.
