1. dole pineapple inc. is concerned that the 16-ounce can of sliced pineapple is being overfilled. assume the standard deviation of the process (population) is .03 ounces. the quality control department took a random sample of 50 cans and found that the arithmetic mean weight was 16.05 ounces. at the 5 percent level of significance, can we conclude that the mean weight is greater than 16 ounces?

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 .

your answer is d 2,500
