Answer:
Ther has been an increase in the selling time.
Step-by-step explanation:
Step 1. Specify the null hypotesis
In this case, we have to demonstrate that the selling time is now different than before the drought.
Step 2. Choose a significance level
In this problem, is 0.10
Step 3. Compute the mean
In this case, the mean of the sample is 94.
Step 4. Compute the probability value (p) of obtaining a difference between the mean of the sample and the hypothesided value of μ.
The degrees of freedom are calculated as (N-1) = (100-1) = 99. Then we can look up in the t-table (http://davidmlane.com/hyperstat/t-table.html) to calculate the probability value of a t of 1.818 with 99 degrees of freedom. The value of this probability is 0.05.
Step 5. Compare the P-value (0.05) with the significance level (0.10). Since the P-value is less than the significance level, the effect is significant.
Since the effect is significant, the null hypotesis is rejected.
It is concluded that the mean of the selling time has changed (increase) from its previous value.
Answer:
A - Solomon read of the book each night.
B - The total number of pages in the book are 105.
Step-by-step explanation:
We are given that,
Solomon has read of a book.
So, of the book is left to be read.
Ques A: We have that,
In 5 nights, Solomon read of the book.
So, on 1 night, he will read, =
of the book.
Thus, Solomon read of the book each night.
Ques B: Let the total pages of the book = x.
Solomon reads 14 pages in 1 night. So, he reads, 14 × 5 = 70 pages in 5 nights.
Since, these 70 pages represent the of the book, he read in 5 nights.
So, of the total pages = 70
i.e.
i.e. x= 105
Hence, the total number of pages in the book are 105.
Answer:
1.73 hours
Step-by-step explanation:
This can be solved with proportions.
Cross multiply and you get:
Divide by 2.58 gallons and you get:
And to find out the number of hours that is, divide by 60 and you get 1.73 hours.
