Answer: a. confidence level.
Step-by-step explanation:
Given : A newspaper provided a "snapshot" illustrating poll results from 1910 professionals who interview job applicants.
i.e. Sample size : n= 1910
The illustration showed that 26% of them said the biggest interview turnoff is that the applicant did not make an effort to learn about the job or the company.
The point estimate of the proportion of job applicants said the biggest interview turnoff is that the applicant did not make an effort to learn about the job or the company = p=0.26
[Note : The point estimate of the population proportion is basically the sample proportion.]
The margin of error was given as plus or minus 3 ±3 percentage points.
But confidence level is necessary to describe the margin of error .
A confidence interval tells how sure you are about the margin of error .
Thus , the important feature of the poll was omitted = confidence level
The distance from the point to the plane is 21. 7
<h3>How to determine the distance</h3>
From the information given, we have the following deductions;
The plane 9x - y - 4z = -52
The points ( 3, 2 , -2 ) are designated x ,y , z and x = 3 , y = 2, z = -2
The formula for a point to a plane is expressed as;
Distance =
Substitute the values
Distance =
Distance =
Distance = 21. 7
Thus, the distance from the point to the plane is 21. 7

Answer: 1,665
To find the product rewrite 444 and 3 3/4 as fractions: 444 x 3 3/4= 444/1 x 15/4. Multiply 444/1 x 15/4= 6,660/4. Divide 6,660 x 4= 1,665. So the business man is about 6,660/4 or 1,665 feet tall.
Answer:
The number zero (0) is a rational number.
Step-by-step explanation:
The number zero can be written as a ratio of two integers, thus it is indeed a rational number. This statement is TRUE.
Answer: 2.46
Step-by-step explanation:
Formula for x-score is given by :-
, where = Sample mean , = population mean, = population standard deviation, n= sample size.
As per given , n=10
= $29,056
= $3,339
= $31,650
Then,
Hence, the z-score = 2.46
