A store manager wants to investigate customer spending in his store. He randomly selects 30 customers and records their purchase total. He finds the mean to be $125 and the standard deviation to be $32. Construct and interpret a 95% confidence interval for the true mean purchase total for all customers. Use this table to determine the appropriate value of t*. Enter the degrees of freedom and the value of t* (exactly as you see it written in the table). Degrees of freedom = t* =

step-by-step explanation:

step-by-step explanation:

7+2=9

215.92 dollars is the answer

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
