Answer:
(5.240 ; 8.760)
Step-by-step explanation:
Given :
Sample mean, xbar = 7
Standard deviation, s = 2.29
Sample size, n = 9
95% confidence interval for the population mean :
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/sqrt(n)
Tcritical at 0.05 ; df = 8 = 2.306
Margin of Error = 2.306 * 2.29/sqrt(9)
Margin of Error = 1.760
Lower boundary = (7 - 1.760) = 5.240
Upper boundary = (7 + 1.760) = 8.760
(5.240 ; 8.760)

Answer:
She has been a member of the gym for seven months
Step-by-step explanation:
In this question, we are asked to calculate the number of months a customer has been a member of a gym, given the pricing template of the gym.
Now, as we can see from the question, there are two kinds of fees to be paid. The flat fee and the subscript class.
First, let’s represent the number of months she has been a member of the gym by m. This means the total amount of money she has paid for m months would be m * 19.99m
Now, recall, we have a flat fee of $68, adding this to the total monthly payment for m months bring the wages to 19.99m + 68
This is said to equal $207.93
This means;
19.99m + 68 = 207.93
19.99m = 207.93 -68
19.99m = 139.93
m = 139.93/19.99 = 7
Answer:
-7
Step-by-step explanation:
there are 16 increments in total, and half are labeled
so the answer is -7 because if the increments are 1 and it is left of zero, so do 7*-1 because it is to the left
