An article investigated the consumption of caffeine among women. A sample of 53 women were asked to monitor their caffeine intake over the course of one day. The mean amount of caffeine consumed in the sample of women was 232.082 mg with a standard deviation of 217.129 mg. In the article, researchers would like to include a 99% confidence interval. With 99% confidence, we estimate the mean amount of caffeine consumed by women is between __mg and ___mg. (Round the limits of your interval to 4 decimal places.)

step-by-step explanation:

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.

to convert it in decimal, we divide it by 100, we get

hence, 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:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
