A frozen food company uses a machine that packages okra in six ounce portions. A sample of 5454 packages of okra has a variance of 0.440.44. Construct the 98%98% confidence interval to estimate the variance of the weights of the packages prepared by the machine. Round your answers to two decimal places.

98% confidence interval: (0.29, 0.73)      

Step-by-step explanation:

We are given the following in the question:

Sample size,n = 54

Sample variance =

Significance level = 0.02

Degree of freedom = n - 1 = 53

We use chi-square to find the confidence interval for population variance.

Formula:

Putting values, we get,

is the required 98% confidence interval for the variance of the weights of the packages prepared by the machine.

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
