Answer:
Claim : The mean weight is greater than 16 ounces
x = 16.05
n = 50
Since n > 30 and population standard deviation is given
So, we will use z test
Substitute the values
Critical value at 0.05 significance level is 1.645
z statistic > critical value
So, we reject the null hypothesis
So, we can conclude that the mean weight is greater than 16 ounces .
