Triana buys new furniture for $4200 and puts it on her credit card.She will pay 18% interest for 18 months and must make monthly

DerKrebs [107]

Answer:

$623.64

Step-by-step explanation:

To determine the money she could have saved if she paid the furniture in full, you have to determine the total amount she will pay when she completes the 18 payments and subtract the price of the furniture from that:

Total amount= 267.98*18

Total amount=4,823.64

$4,823.64-$4,200= $623.64

She have saved $623.64 if she paid for the furniture in full.

Determine whether the normal sampling distribution can be used. The claim is p < 0.015 and the sample size is n

Svetradugi [14.3K]

Complete Question

Determine whether the normal sampling distribution can be used. The claim is p < 0.015 and the sample size is n=150

Answer:

Normal sampling distribution can not be used

Step-by-step explanation:

From the question we are told that

The null hypothesis is $H_o : p = 0.015$

The alternative hypothesis is $H_a : p < 0.015$

The sample size is n= 150

Generally in order to use normal sampling distribution

The value $np \ge 5$

$np = 0.015 * 150$

$np = 2.25$

Given that $np < 5$ normal sampling distribution can not be used
