Answer:

c. About half of the students want the grant money to be used to buy more laptops for student use

Step-by-step explanation:

Given that your school has received a grant to upgrade the school library.

Sample size = 50

Sample proportion for students who would like to see more laptops available for student use=\frac{27}{50} =0.54

H_0: p = 0.5\\H_a: p >0.5

(Right tailed test at 5% level)

p difference = 0.04

Std error of p = \sqrt{pq/n} \\=\sqrt{\frac{0.5*0.5}{50} } \\=0.0707

Z= p diff/std error = 0.5656

p value = 0.2858

Since p >0.05 we accept null hypothesis.i.e p = 0.5

c. About half of the students want the grant money to be used to buy more laptops for student use

Answer:

The correct answer is C: About half of the students want the grant money to be used to buy more laptops for student use

Step-by-step explanation:

You simply do the proportion based on the sample data and solve the fraction, which is around 50%. This means about half of the real population wanted grand money used for more laptops. (This is also the correct answer on edge)

Kate and Ashton have been approved for a $200,000 15 year mortgage with an APR of 5.5%. How much of their first monthly payment
Ksju [112]
$920 would be the amount of interest in the first payment.

We convert the decimal to a monthly amount first.  (5.5/100)/12 = 0.0046.  We then multiply this by the amount of the loan, 200,000:

200000*0.0046 = 920.

$920 of the first month's payment would go towards interest.

To find the percentage of the payment, you would divide this amount by the amount of the first month's payment.

a quarterback is sacked for a loss of 5 yards.On the next day his team loses 15 yards.Then the team gains 12 yards on the third
Veronika [31]

Assume it is first down and ten in this problem. When you lose 5 yards on the sack, you are 5 yards further away. So now, it is second and 15. Then, they lose another 15 yards, so it's now third and 30. The final play is that they gain 12 yards, meaning after all the plays it is fourth down and eighteen yards to go.

In math symbols, 0 is where the first down marker is. You start at -10.

First play, the sack: -10 - 5 = -15

Second play: -15 - 15 = -30

Third play: -30 + 12 = -18.

Looks like you have to punt on fourth down :)
