1) Note that for a student there may exist two cases either the student committed a cheating 
or he/she didn’t. Let us define a random variable Xi which takes two value. Xi takes 
value 1 if the ith student were involved in some kind of cheating and 0 if he/she did not. 
Now if p is the probability or proportion of commiting a cheating then clearly, 
Xi~Bernoulli (p) 
Now we have 90 students in this sample so i can take values 1,2,3,…,90. 
Using the result “Sum of Bernoulli random variables follow a Binomial distribution” 
∑X ~ Binomial (90,p).
Now we know the 100(1-α)% confidence interval in this case is obtained from the 
probability that this interval will contain the value of the true parameter is  (1-α). 
Now note the following fact, 
here the sample size is 90 and we know if the sample size is more than 30 we can 
consider it as large sample and we can use Central Limit Theorem to show that the test 
statistic follows a standard normal distribution. Similarly here if  ̂ is the sample 
proportion of students who were involved in some kind of cheating then,
Z=
 ̂  
√ ̂ (   ̂)   
 which follows a standard normal distribution if  ̂      are almost same.
So the 100(1-α)% CI can be obtained from the probability,
P(|Z| ≤ Z1-α/2 ) = 1-α. 
Which gives the confidence interval as, 
[ ̂- Z1-α/2√ ̂  (   ̂)   ,  ̂+ Z1-α/2√ ̂  (   ̂)   ]
Now based on the above results let’s find out the required Confidence intervals. 
Since we need to calculate the 95% confidence interval so α=0.
