Using the binomial distribution, it is found that since 16 is more than 2.5 standard deviations above the mean, it is a unusually high number.

<h3>What is the binomial probability distribution?</h3>

It is the probability of <u>exactly x successes on n repeated trials, with p probability</u> of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

The standard deviation of the binomial distribution is:

$\sqrt{V(X)} = \sqrt{np(1-p)}$

A measure is considered to be unusually high if it is more than 2.5 standard deviations above the mean.

In this problem, we hav ehtat:

34% of companies reject candidates because of information found on their social media, hence p = 0.34.

27 human resource professionals are randomly selected, hence n = 27.

Then, we find the threshold for unusually high values as follows:

E(X) = np = 27 x 0.34 = 9.18

$\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{27(0.34)(0.66)} = 2.46$

T = 9.18 + 2 x 2.46 = 14.1.

Since 16 is more than 2.5 standard deviations above the mean, it is a unusually high number.

In normal riding posture, the proper position for the elbows is:

Svet_ta [14]

Assuming the riding position pertains to biking, the best position for the elbows is bending them. In doing so, you would relieve some pressure on your elbows, wrists and hands. This could also help you absorb shock when passing over bumpy roads through your arms.

The number of work stoppages in the automobile industry for selected monthes are 6,0,10,14,8,0 .What is the median number and wh

Ratling [72]

Answer: median is 7, the type of mode is unimodal

Explanation:

median is 7 because there are 6 numbers. Based on the rules if the number of scores is even then get the two middle most numbers (after arranging the scores in increasing order) then get the average so 6 + 8 is 14 and the average is 7.

the mode is most occured number. So the most occured number is 0. And since we only have 1 type of number occured more than one time so that is unimodal.
