He should place the picture at 6.75 inches from the edge of the wall.
<u><em>Explanation</em></u>
According to the below diagram, O is the center of the wall and <u>AB is the distance of the picture from the edge of the wall. </u>
As the length of the wall is inches or 31.75 inches , so the half length of the wall
inches.
Now, the length of the picture is inches or 18.25 inches, so the half length of the picture
inches.
Thus, inches
So, he should place the picture at 6.75 inches from the edge of the wall.
Answer:
Yes, this sample provide enough evidence to support the delivery time claim made by the pizza place.
Step-by-step explanation:
We are given that a pizza place recently hired additional drivers and as a result now claims that its average delivery time for orders is under 44 minutes.
A sample of 39 customer deliveries was examined, and the average delivery time was found to be 40.5 minutes. Historically, the standard deviation for delivery time is 11.3 minutes.
From this, X bar = 40.5 , = 11.3 ,
= 44 and sample, n = 39
Null Hypothesis, :
>= 44
Alternate Hypothesis, :
< 44
The test statistics used here will be;
T.S. = ~ N(0,1)
So, Test statistics = = -1.93
Now, at 5% significance level the z score table gives critical value of -1.6449 as it is one-tail test.
<em>Since our test statistics is less than the critical value as -1.93 < -1.6449, so we have sufficient evidence to reject null hypothesis and conclude that the average delivery time for orders is under 44 minutes.</em>
