Give an estimate of the mean hardness that you would expect after 37 and 41 hours; and a 85% confidence interval for each estima
Jlenok [28]
The predicted value of hardness at 37 hours is 243.87 and an 85% confidence interval for the mean hardness is (242.12, 245.61). At 41 hours, the predicted hardness is 252 and an 85% confidence interval for mean hardness is (249.83, 254.18). The confidence interval for X is equals to 41 which is wider because the value 41 is farther away from the sample mean X than is 37. As an outcome, the standard error for the prediction is larger.

alex buys a home for $276,400. his home is predicted to increase in value 3.5% each year. What is the predicted value of alex's
Katarina [22]
276400(0.035) = $9674 the equivalent value in dollar for every increase in the house then multiplied by 25. $9674*(25) = $241850 + the current value of Alex's home. $276400+ $241850 = $518250 that would be the value of Alex's home in 25  years. The percentage is (518250-276400)/ 276400 =0.875 *100 = 87.5 % increase in value. I hope this would help.

Suppose the postal service charges $10.30 per pound on the package shipped to England what is this rate in dollars per ounce
frosja888 [35]

Given:

The postal service charges $10.30 per pound on the package shipped to England.

To find:

The rate in dollars per ounce.

Solution:

We know that,

1 pound = 16 ounce

1 Dollar per pound = \dfrac{1}{16} dollar per ounce.

1 Dollar per pound = 0.0625  dollar per ounce.

We have, the postal service charges $10.30 per pound on the package shipped to England.

Using the above conversion, we get

$10.30 Dollar per pound = 10.30\times 0.0625
 dollar per ounce

$10.30 Dollar per pound = 0.64375
 dollar per ounce

Therefore, the required rate is $0.64375  per ounce.
