Answer:
The mean apple weight is different from 8oz
Step-by-step explanation:
Claim : An apple farm claims that the average weight of all their apples is 8oz.
n = 20
Standard deviation =s = 0.95
Since n < 30
So we will use t-test
x = 7.77
Substitute the values :
Since we are not given the significance level
So, we will take 5%
So,α = 0.05
Degree of freedom = df = n-1 = 20-1 = 19
So, using t table
Since t critical > t statistic
So, we accept the null hypothesis.
So, The mean apple weight is different from 8oz
