Answer:

Step-by-step explanation:

The given statement is,"9 is subtract from the product of 7 and 3".

The product of 7 and 3 means, we need to multiply 7 and 3. So,

7 × 3 = 21

9 is subtract from the product of 7 and 3 means, 21 - 9 = 12.

Hence, the value of 9 is subtract from the product of 7 and 3 is 12.

Answer:

0.288 < p < 0.338

Step-by-step explanation:

We have 2331 adults polled and 730 said they believe in UFOs. We are to construct a 99% confidence interval for the population proportion. We are told to round to 3 decimal places as needed.

We need to find p-hat and q-hat

p-hat = 730/2331 = 0.313

q-hat = 1 - p-hat = 1 - 0.313 = 0.687

Since the sample size is greater than 30, we use a z-value for 99% confidence, which is 2.575

See attached photo for the construction of the confidence interval
