Since he’s already at -15, if he writes a check for 7 then he’s subtracting more from his account.
So, -15-7=-22
Let p be
the population proportion. <span>
We have p=0.60, n=200 and we are asked to find
P(^p<0.58). </span>
The thumb of the rule is since n*p = 200*0.60
and n*(1-p)= 200*(1-0.60) = 80 are both at least greater than 5, then n is
considered to be large and hence the sampling distribution of sample
proportion-^p will follow the z standard normal distribution. Hence this
sampling distribution will have the mean of all sample proportions- U^p = p =
0.60 and the standard deviation of all sample proportions- δ^p = √[p*(1-p)/n] =
√[0.60*(1-0.60)/200] = √0.0012.
So, the probability that the sample proportion
is less than 0.58
= P(^p<0.58)
= P{[(^p-U^p)/√[p*(1-p)/n]<[(0.58-0.60)/√0...
= P(z<-0.58)
= P(z<0) - P(-0.58<z<0)
= 0.5 - 0.2190
= 0.281
<span>So, there is 0.281 or 28.1% probability that the
sample proportion is less than 0.58. </span>
The correct option is B. Reread the directions for each section.
If you have time left after completing the test don't reread the directions for each section.
<h3>What is meant
previewing a test?</h3>
In order to find the various problem kinds and their point values during the test preview, you must read the complete test. Mark the questions that you can answer quickly and easily.
The benefits of previewing the test are-
- You will probably be given credit for the answers even if you accidentally copied them from the scratch paper.
- Your effort on the scratch paper can earn you some points if a thoughtless mistake causes you to get the answer wrong.
- If you do make a mistake, it will be simpler to find it when the instructor goes through the test.
- By doing this, you can avoid making the same errors on your next exam.
Therefore, resolve each issue by re-entering the solution into the equation or performing the opposing operation needed to provide the appropriate response. Do not leave the testing room until the bell has rung or after you have gone over each problem twice.

The complete question is-
All of the following are suggestions of things to do if you have time left after completing the test except
A. Look at your answer sheet to make sure its filled properly
B. Reread the directions for each section
C. Return to the questioms you were unsure of
D. Make sure your answers correspond to the correct questions
13x u add parentheses since two negatives positive
The commutative property of 9+8=17 is 8+9=17 because the commutative property states that it doesn't matter the order of the number but as long as u get the same answer.
