Hey, since there are multiple sub-parts question posted, we will answer first three sub-parts. If you want any specific sub-part question to be answered then please submit that sub-part question only or specify the sub-part question number in your message.

Step 2

a) Number of successes:

It is given that the sample had 32% successes.

Let x denotes the number of successes.

The number of successes is obtained as 224, from the calculations given below:

Step 3

b) Computation of p-hat:

The value of p-hat is obtained as 0.32, from the...
