Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x overbarequals102

.04​, y overbarequals101.55​, requals0.856​, ​P-valueequals​0.000, and ModifyingAbove y with caret equals 25.05 plus 0.75 x​, where x represents the IQ score of the younger child. Find the best predicted value of ModifyingAbove y with caret given that the younger child has an IQ of 95​? Use a significance level of 0.05.

Answer:

96.3

Step-by-step explanation:

The equation for predicting variable y is

y=25.05+0.75x.

Here x is the IQ of younger child.

We have to find the predicted value of y given that the younger child's IQ is 95. It can be computed by putting x=95 in the above equation.

So,

y=25.05+0.75*95

y=25.05+71.25

y=96.3

Thus, the best predicted value of y given that the younger child has an IQ of 95​ is 96.3.

The cost of health insurance is $900 per month. The cost of an operation for a dramatic injury is $500,000. The chances of someo
lord [1]

Answer:

Yes, It is better to buy the insurance.

Step-by-step explanation:

Given Data:

Cost of Health Insurance for a month = 900$ per month

As 20 Years = 20*12 months = 240 months

Cost of Health Insurance for 20 years = 900 * 240

Cost of Health Insurance for 20 years = 216,000$

Insurance claim in case of having dramatic injury = Cost of Dramatic Injury = 500,000$

Insurance claim in case of having no dramatic injury = 0$

Chances of dramatic injury in 20 years = P(A) = 47.3%

Chances of not having dramatic injury in 20 years = P(B) = 100% - 47.3%

Chances of not having dramatic injury in 20 years = P(B) = 52.7%

Expected Insurance Claim for 20 years:

Expected Insurance Claim for 20 years = (Chances of having dramatic injury in 20 years * Insurance claim) + (Chances of not having dramatic injury * Insurance claim)

Expected Insurance Claim for 20 years = P(A) * 500,000$ + P(B) * 0$

Expected Insurance Claim for 20 years = 47.3% * 500,000 + 52.7% * 0

Expected Insurance Claim for 20 years = 236500 + 0

Expected Insurance Claim for 20 years = 236,500$

Expected Profit:

As expected insurance claim is 236,500$ is more than the cost of health insurance for 20 years and we are expected to have profit of 20,500$, thus we should take the health insurance.

Step-by-step explanation:

As the expression given in the question be as follow.

−7n+2 and 2n - 1 .

Subtracted −7n+2 from 2n - 1 .

= 2n - 1 - (-7n + 2)

Open the bracket

= 2n - 1 + 7n - 2

Simplify the above

= 9n - 3

Therefore Subtracting  −7n+2 ​​from 2n−1 ​ is 9n - 3.
