A newspaper reports that the population mean annual salary of a full-time college professor in a certain region is exactly $127,

Leya [2.2K]

Answer:

Option B) Fail to reject the null hypothesis that the true population mean annual salary of full-time college professors in the region is equal to $127,000.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = $127,000

Sample mean, $\bar{x}$ = $126,092

Sample size, n = 160

Alpha, α = 0.10

Sample standard deviation, σ = $8,509

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 127000\text{ dollars}\\H_A: \mu \neq 127,000\text{ dollars}$

We use Two-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

$t_{stat} = -1.35$

Now, $t_{critical} \text{ at 0.10 level of significance, 159 degree of freedom } = \pm 1.654$

Since,

The calculated t-statistic lies in the acceptance region, we fail to reject and accept the null hypothesis.

Option B) Fail to reject the null hypothesis that the true population mean annual salary of full-time college professors in the region is equal to $127,000.

Two sides of an acute triangle are 8 and 15. how many possible lengths are there for the third side, if it is a positive integer

Misha Larkins [42]

In an accute triangle the 3 angles are less than 90°.

The minimum lenght of the third side is if the other two sides form the lowest possible angle (close to 0 degrees), in which case the length approximates to zero, so if the number is an integer, the minimum length of the fhird side is 1.

The maximum length of the third side is if it is close to the hypotenuse of a right triangle with legs 8 and 15 =>

hypotenuse^2 = 15^2 + 8^2 = 289 => hypotenuse =17. So, the lenght of the third side must be less than 17.

So, the possible lengths of the third side are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16.
