UkoKoshka [18]

Answer:

The 90% CI for p is (0.53, 0.83)

Step-by-step explanation:

We have to develop a 90% confidence interval for the proportion of all students at the college that have met with a counselor to develop an educational plan.

We have a sample of size 25, where the sample proportion is:

$p=X/n=17/25=0.68$

The critical value of z for a 90% CI is z=1.645.

The margin of error is then:

$E=z\cdot\sqrt{\dfrac{p(1-p)}{n}}=1.645*\sqrt{\dfrac{0.68*0.32}{25}}=1.645*\sqrt{0.008704}=1.645*0.093\\\\\\E=0.15$

Then, the lower and upper bound of the confidence interval are:

$LL=\hat p-E=0.68-0.15=0.53\\\\UL=\hat p+E=0.68+0.15=0.83$

The 90% CI for p is (0.53, 0.83)

A rental car company charges $68.80 per day to rent a car and $0.08

viktelen [127]

Answer:

5 days maximum

Step-by-step explanation:

Given

Daily charge = $68.80
Charge per mile = $0.08
Target distance = 325 miles
Money limit = $370

Required inequality:

68.8d + 325*0.08 ≤ 370

Solving for d:

68.8d + 26 ≤ 370
68.8d ≤ 344
d ≤ 344/68.8
d ≤ 5

Up to 5 days is the answer
