Afrozen food company uses a machine that packages okra in six ounce portions. a sample of 54 packages of okra has a variance of 0.44. construct the 98% confidence interval to estimate the variance of the weights of the packages prepared by the machine. round your answers to two decimal places. lower endpoint and upper endpoint

Interval would be (0.29,0.58).

Step-by-step explanation:

Since we have given

n = Sample size = 54

Variance = 0.44

we need to find 98% confidence interval to estimate the variance.

So, we will use "Chi square distribution"

For this , we will find

df = n-1=54-1=53

Interval would be

similarly,

So, it becomes,

Hence, interval would be (0.29,0.58).

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
