Answer:
The confidence interval has a lower limit of 0.546 and an upper limit of 0.675.
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 z-score that has a p-value of
.
In 2017, a random sample of 154 individuals who graduated from high school 12 months prior was selected. From this sample, 94 students were found to be enrolled in college or a trade school.
This means that 
90% confidence level
So
, z is the value of Z that has a p-value of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The confidence interval has a lower limit of 0.546 and an upper limit of 0.675.
The largest number of sweets that cannot be purchased exactly is 113.
43/100 = 0.43
21/2/100 = 0.105
13.6/100 = 0.136
521/100 = 5.21
No, for example 13 is a prime number and reversing it is 31 which is also a prime number.
11=11-also prime
13=31-also prime
23=32-NOT PRIME
23=92-NOT PRIME
