When 258 college students are randomly selected and surveyed, it is found that 106 own a car. find a 99% confidence interval for the true proportion of all college students who own a car. 0.351 < p < 0.471 0.332 < p < 0.490 0.339 < p < 0.482 0.360 < p < 0.461

0.332 < p < 0.490

Step-by-step explanation:

We know that the confidence interval for population proportion is given by :-

, where n= sample size

= sample proportion

z* = critical z-value.

As per given , we have

n= 258

Sample proportion of college students who own a car =

Critical z-value for 99% confidence interval is 2.576. (By z-table)

Therefore , the  99% confidence interval for the true proportion(p) of all college students who own a car will be :

Hence, a 99% confidence interval for the true proportion of all college students who own a car : 0.332 < p < 0.490

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
