Answer:
The total percentage return is 26.19
Step-by-step explanation:
Given as :
The amount paid for three years = $ 2800
So, Total amount paid for three years = $ 2800 × 3 = $ 8400
The return amount after three years = $ 2200
The time period = 3 years
Let the percentage return = x %
So, According to question
x % of $ 8400 = $ 2200
Or, x % =
Or, =
∴ x = × 100
I.e x = 26.19
Hence The total percentage return is 26.19 Answer

Answer:
The p value would be given by:
For this case since th p value is lower than the significance level of0.05 we have enough evidence to reject the null hypothesis and we can conclude that the true mean for this case is significantly different from 46.7 MPG
Step-by-step explanation:
Information given
represent the mean
represent the population standard deviation
sample size
represent the value to verify
represent the significance level for the hypothesis test.
z would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true mean for this case is 46.7, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Since we know the population deviation the statistic is given by:
(1)
Replacing we got:
The p value would be given by:
For this case since th p value is lower than the significance level of0.05 we have enough evidence to reject the null hypothesis and we can conclude that the true mean for this case is significantly different from 46.7 MPG
