A national business magazine reports that the mean age of retirement for women executives is 61.7. A women’s rights organization

Marina CMI [18]

Answer:

The calculated value |Z| = |-2.0375| = 2.0375<2.0541.96 at 0.02 level of significance

A women’s rights organization believes that the average value does not accurately depict the current trend in retirement.

Step-by-step explanation:

Step(i):-

Given that the mean age of retirement for women, executives is 61.7

Given mean of the Population = 61.7

Given that the size of the sample 'n' = 82

Given that the mean of sample x⁻ = 60.8

Given that the standard deviation 'σ' = 4.0years

Step(ii):-

Null hypothesis:H₀: μ ≠ 61.7

Alternative Hypothesis: H₁: μ = 61.7

Test statistic

$Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{60.8-61.7}{\frac{4.0}{\sqrt{82} } }$

Z = -2.0375

|Z| = |-2.0375| = 2.0375< 2.054 at 0.02 level of significance

Final answer:-

The calculated value |Z| = |-2.0375| = 2.0375 <2.054 at 0.02 level of significance

A women’s rights organization believes that the average value does not accurately depict the current trend in retirement.

Find the measure of angle F

Tema [17]

Answer:

∠ F = 80°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

Sum the interior angles and equate to 720

7x + 7x + 4x + 7x + 7x + 4x = 720

36x = 720 ( divide both sides by 36 )

x = 20

Then

∠ F = 4x = 4 × 20° = 80°

You have just installed a SOHO router in your customer's home and the owner has called you saying that Internet gaming is too sl

Marrrta [24]

Answer:

Step-by-step explanation: Wireless comunication can be improved on several ways. From the software side and from the hardware side.

First, is good to know that Wifi protocol provides a latency that can go from 10 ms to 40 ms, on the best scenarios. This is natural from it, so it should be taken in account. The only way to avoid this, is using a wired connection.

From the software side, WiFi protocols works on Channels, this are predetermined frecuencies on which the same WiFi signal can travel. Several sources nearby on a same Channel can cause interference, so a good way to avoid latency is to switch to another less poblated Channel. Routers Manufacturers can set all their devices to work on a same channel, so several costumer which those devices can cause inteference between each other if they are near.

From hardware, the WiFi is affected by the environment, walls can damp the signal by a significative percentage, so it is good to have a Line Of Sign between the user and the Wifi Source.

Also, cables and electric conductors can cause interference too. All conductor which a current passing through it will generated a Magnetic Field (Ampere's Law), this will inteference with the Wifi signal also. Bigger Electric Devices, like washmachines and heater can cause lot of inteference.

So, to speed up the gaming experience, can be the following:

Switch the Channel to another less used.

Make sure the device has Line of Sight with the Router

Check the Router is not near from any electric device that could be causing interference.

If the above is not enough, use a wired connection.
