Answer:
E) we will use t- distribution because is un-known,n<30
the confidence interval is (0.0338,0.0392)
Step-by-step explanation:
<u>Step:-1</u>
Given sample size is n = 23<30 mortgage institutions
The mean interest rate 'x' = 0.0365
The standard deviation 'S' = 0.0046
the degree of freedom = n-1 = 23-1=22
99% of confidence intervals
(from tabulated value).

Confidence interval is


the mean value is lies between in this confidence interval
(0.0338,0.0392).
<u>Answer:-</u>
<u>using t- distribution because is unknown,n<30,and the interest rates are not normally distributed.</u>
About 3.606, if you round it.
Answer:
Step-by-step explanation:
Part A:
3x+12+7x+88=180
10x+100=180
10×=80
X=8
Part B:
m<RPS=3x+12
(3*8)+12
=36
3/5 is bigger because 4/7 = 20/35 and 3/5 = 21/35
Answer:
