Working out and explanation would be great!

A machine that dispenses salad dressings is working properly when the mean amount dispensed is 330 mL. The population standard deviation of the amount dispensed is 4 mL. A sample of 50 bottles is selected and the filling line is stopped if there is evidence that the mean amount dispensed is different from 330 mL. Suppose that the mean amount dispensed in a particular sample of 50 bottles is 329.7 mL. a. Is there evidence that the mean amount dispensed is different from 330 mL? (Use a 0.05 level of significance.) b. Compute the p-value and interpret its meaning Click here to view page 1 of the cumulative standardised normal distribution table. Click here to view page 2 of the cumulative standardised normal distribution table. a. Let u be the population mean. Determine the null hypothesis, Ho, and the alternative hypothesis, H1 - O A. Ho: us 330 O B. Ho: H# 330 H1: H > 330 H1: H = 330 O C. Ho: H = 330 O D. Ho: H 2 330 H1: H # 330 H1: H
