Your answer is A. Jake paid $49,869 for the cabin
Answer:
Step-by-step explanation:
Proportion of retired people under the age of 65 would return to work on a full-time basis if a suitable job were available = 60/100 = 0.6 = P
Null hypothesis: P ≤ 0.6
Alternative: P > 0.6
First, to calculate the hypothesis test, lets workout the standard deviation
SD = √[ P x ( 1 - P ) / n ]
where P = 0.6, 1 - P = 0.4, n = 500
SD = √[ (0.6 x 0.4) / 500]
SD = √ (0.24 / 500)
SD = √0.00048
SD = 0.022
To calculate for the test statistic, we have:
z = (p - P) / σ where p = 315/500 = 0.63, P = 0.6, σ = 0.022
z = (0.63 - 0.6) / 0.022
z = 0.03/0.022
z = 1.36
At the 2% level of significance, the p value is less than 98% confidence level, thus we reject the null hypothesis and conclude that more than 60% would return to work.
9. Let p = Pico
3/4p = 18
10. Let h = height with pedestal and foundation
151 + h = 305
11. Let m = Meredith
19 = 3 + 2m
12. Let p = number of pizzas, $5 off is - 5 from regular price
3p - 5 = 21.75
13. Option C.
14. Option A.
15. Let w = last week's miles
w =

(12) + 3
The word "half" tells you to use 1/2 in the equation. The phrase "three more than" tells you to use + 3. We multiply 1/2 by 12 (or divide 12 by 2; it's the same thing) because we are taking half of the miles Carmen ran "this week" as stated in the problem.
