Answer:
They changed 5m into a positive when it should've stayed as a negative until you isolate the variable m at the end, making m actually equal -7.
Step-by-step explanation:
-5m - 16 = 19
-5m = 19 + 16
-5m = 35
m = 35/-5
m = -7

Step-by-step explanation:
Answer:
Question 1:
(b) 4,445
Question 2:
(c) 2.1%
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is of:
95% confidence level
So , z is the value of Z that has a pvalue of , so .
Question 1:
We have no previous estimate for the population proportion, so we use .
The sample size is n for which M = 0.015. So
Samples above this value should be used, and the smaller sample above this value is of 4445, so the answer is given by option b.
Question 2:
Now we find M for which .
So 2.1%, and the correct answer is given by option c.
