Answer:
: The average time postal employees have worked for the postal service is 7 years.
: The average time postal employees have worked for the postal service is not 7 years.
Step-by-step explanation:
We need to know the significance level to decide if the average time worked for the postal service has changed according to the the random sample of 100 postal employees working time.
Aur hypothesis would use two tailed critical region, sice the hypothesis is an equality.
Just subtract 45 - 28 = 17 lollipops
Hope this helps!!!
Answer:
Yes, the probability distribution is valid.
Step-by-step explanation:
Given :
Income range ___ midpoint(x) ___ %
5 - 15 __________ 10 _____20%
15 - 25 _________ 20 _____13%
25- 35 _________ 30 _____ 21%
35 - 45 _________40 _____ 17%
45 - 55_________ 40 ____ 20%
55 or more _______ 50 _____9%
Yes, we do have a valid probability distributuon ; as the summation of the percentage values is equal to 100%
ANSWER
169.1m
EXPLANATION
From the diagram, the horizontal distance traveled is x meters.
This is the side adjacent to the 6° angle.
Since we know the hypotenuse to be 170m, we use the cosine ratio to find the value of x.
.
This implies that
x=170cos(6°)
x=169.0687222
To the nearest tenth, the horizontal disance travelled is 169.1m
