Suppose a machine is set to fill a candy package with 56 candies per bag. A sample of 9 bags results in a mean of 57 and a sample standard deviation of 1.0. How many degrees of freedom are used to test the hypothesis?
Homework Answers
Solution:-
Given that,
mean = 
= 57
standard deviation = 
= 1.0
n = 9
degrees of freedom = n - 1 = 9 - 1 = 8

(1 point) Suppose that you have purchased a filling machine for candy bags that is supposed to fill each bag with 14 oz of candy. Assume that the weights of filled bags are approximately normally distributed. A random sample of 9 bags yields the following data (in oz): 13.13 13.29 13 13.42 14.52 13.59 14.79 14.59 14.59 Using a 0.05, can you conclude that the mean fill weight is actually less than 14 by computing the following: (a) the degree...

A candy company sells bags of candy that are supposed to have an average of 40 pieces per bag, with = 9 . A random sample of 94 candy bags shows the average number of candies per box to be 43.1. Using a 1% level of significance, test that the average number of candies per bag is more than 40. Determine the p-value and interpret the results.

Calculate the mean, median, and standard deviation for the total number of candies (per bag). Construct a histogram of the total number of candies (per bag). Use the z-score method to identify any potential outliers and outliers. Assume the total number of candies is normally distributed, calculate the probability that a randomly sampled bag has at least 55 candies in a bag. If a random sample of 50 bags is selected, find the probability that the mean number of candies...

A sample of 14 small bags of the same brand of candies was selected. Assume that the population distribution of bag weights is normal. The weight of each bag was then recorded. The mean weight was 3 ounces with a standard deviation of 0.15 ounces. The population standard deviation is known to be 0.1 ounce. NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed. (In general, you must first prove that...

A manufacturer of chocolate candies uses machines to package candies as they move along a line. Although the packages are labeled 8 oz, the company wants the package to contain a mean of 8.17 oz so that none of the packages contain less than 8 oz. A sample of 50 packages is selected, and the process is stopped if different from 8.17 oz. Suppose that in a particular sample fo 50 packages, the mean ammount dispensed is 8.169 oz with...

Q16. Suppose a random sample of 25 bags of Plain M&M chocolate candies was taken and a 95% confidence interval for the mean weight per bag is (35.7 grams, 39.4 grams). Which statement about the confidence interval is valid? Background: M&Ms is a popular type of chocolate candy that comes in a variety of colors as well as types, which refer to the filling of the candy (e.g., plain-type M&Ms are plain milk chocolate covered in candy coating and peanut-type...
