In a survey of 23312331 adults, 730730 say they believe in UFOs. Construct a 99 %99% confidence interval for the population pro

serg [7]

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

Five less than 25% of a number is twice the difference of the number and 14. Write an equation that could be used to find the nu

Dmitriy789 [7]

Answer:

(n/4) - 5 = 2(n-14)

Step-by-step explanation:

let the number be n

"25% of n" : (25/100)n = n/4

"Five less than 25% of n" : (n/4) - 5

"difference between the number and 14" : n - 14

" twice the difference between the number and 14" : 2(n-14)

Assembling all the parts:

(n/4) - 5 = 2(n-14)
