Answer:
1-5,-0.25,0.3
Step-by-step explanation:
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).
using calculator
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>

Answer:
-2√3+2√15
Step-by-step explanation:
Since the formula for the volume of the cube is width*height*length, we know that 6*12*length=1242. Multiplying it out, we get that 72*length=1242. After that, we can divide 72 from both sides to get 1242/72=length=17.25 inches which I guess is close enough to 17?
