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
Answer:
B
Step-by-step explanation:
-4/2 = -2
-2 + 5 = 3
Answer:
21
Step-by-step explanation:
0 + 1 = 1
1 + 2 = 3
3 + 3 = 6
6 + 4 = 10
10 + 5 = 15
15 + 6 = 21
Each number is added to an increase of 1 - first add 1, then add 2, then add 3,etc
Not listed but next would be 21 + 7 = 28
so it would be 0, 1, 3, 6, 10, 15, 21, 28
Answer:
4.25%
Step-by-step explanation:
<u>Step 1: Calculate the commission paid</u>
<em>Commission = Gross earning - base salary</em>
<em>Commission = 441.3 - 375</em>
Commission = 66.3
<u>Step 2: Calculate the commission sales</u>
<em>Commission sales = Total sales - quota sales</em>
<em>Commission sales = 6560 - 5000</em>
Commission sales = 1560
<u>Step 3: Calculate the rate of commission</u>
<em>x% of 1560 = 66.3</em>
<em>x% * 1560 = 66.3</em>
<em>x% = 0.0425</em>
x = 4.25%
Therefore, the rate of commission was 4.25%.
