Prev Question 8 of 12 Step 1 of 1 01 07 14. A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 413 gram setting. It is believed that the machine is underfilling the bags. A 27 bag sample had a mean of 410 grams with a standard deviation of 26. A level of significance of 0.05 will be used. Assume the population distribution is approximately normal. State the null and alternative hypotheses. Keypad Tables Hide Answer H H Next 23 AM 3/6/2017

Explanation / Answer

1.Ho: Mu = 413g
Ha: Mu!= 413g

2,3. This not a sampl eproportion problem

Sample mean = 410
Pop. Mean = 413
stdev= 26
n=27
alpha = .05
4. test statistic = t = (410-413)/(26/sqrt(27)) = -0.6
5.For t = -.6 and df = n-1=26-1=25 we have a t value which is more than t critical
6.Hence, we dont reject null hypothesos
