The length would be 26 and the width would be 16.
L = length
w = width
p = perimeter
p=72
2L+2w=72
L=w+4
2(w+4) + 2w = 72
2w + 8 + 2w = 72
4w = 64
w = 16
2L + 2(16) = 72
2L + 32 = 72
2L = 52
L = 26
w = 16
L = 26
Answer:
Option (B) a 95% confidence interval does not include the hypothesized value of the parameter
Step-by-step explanation:
Alpha, α = 0.05
We conduct a hypothesis test at 5% significance level.
The null hypothesis will be rejected when
Option (B) a 95% confidence interval does not include the hypothesized value of the parameter
- When a 95% confidence interval is constructed,it contains all the possible values for the parameter being estimated.
- If the value of the parameter stated in the null hypothesis is contained in the 95% confidence interval, then we fail to reject the null hypothesis 0.05 level and accept it.
- If the value stated in the null hypothesis is not in the interval, then we fail to accept the null hypothesis and reject the null hypothesis at the 0.05 level.
Answer:
around 22, or 21.98
Step-by-step explanation:
2/3 of 1668 = 1112, and 1668 - 1112 = 556, so the special will cost $556
