Answer: Total = $200
Step-by-step explanation:
<u>Given information</u>
Money spent on shoes = $20.00
Percent of Money spent on shoes = 10%
<u>Given formula</u>
The total amount of money spent × Percent = Money spent on shoes
⇵
The total amount of money spent = Money spent on shoes / Percent
<u />
<u>Substitute values into the given formula</u>
The total amount of money spent = Money spent on shoes / Percent
Total = (20.00) / (10%)
<u>Convert percentage into decimal</u>
Total = 20.00 / 0.1
<u>Simplify the fraction</u>
Hope this helps!! :)

Answer:
The 90% confidence interval for the true mean number of reproductions per hour for the bacteria is between 11.2 and 11.6 reproductions.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 11.4 - 0.2 = 11.2 reproductions.
The upper end of the interval is the sample mean added to M. So it is 11.4 + 0.2 = 11.6 reproductions.
The 90% confidence interval for the true mean number of reproductions per hour for the bacteria is between 11.2 and 11.6 reproductions.
