You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures: 57.9
25.4
19.8
28.3
60.7
39.4
51.1
63.4

Find the 99% confidence interval. Enter your answer as an open-interval (i. e., parentheses) accurate to two decimal places (because the sample data are reported accurate to one decimal place).

(If you could please show step by step, that would be very helpful!)

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.
