There is no statistical evidence to prove that mean is atleast 60
Step-by-step explanation:
Given that a department store manager believes that the average age of their customers is at least 60.
(Right tailed test)
significance level = 1%
Data given is
70 48 41 68 69 55 70 57 60 83
32 60 72 58 88 48 59 60 56 65

Mean60.93333333
std dev12.00268169
Std error2.155745271
df = 30
Mean difference = 0.93
Test statistic = mean difference/std error
= 0.431405
p value = 0.3346
Since p >0.01 we accept null hypothesis
There is no statistical evidence to prove that mean is atleast 60
