Apopulation is known to have a standard deviation of 26.1. a sample space of 35 items has a mean of 562. construct a 90% confidence interval estimate of the mean of the population. a. 566< μ< 558 b. 555< μ< 569 c.551< μ< 573 d.561< μ< 563

The correct option is B.

Step-by-step explanation:

The value of μ is

Where, is sample mean of the data, z represents the z-score, σ is standard deviation, and n is numbers of samples.

The standard deviation of the sample is 26.1. A sample space of 35 items has a mean of 562. construct a 90% confidence interval estimate of the mean of the population.

From the z-table the value of z at 90% confidence interval with 34 degree of freedom is 1.691.

Therefore option B is correct.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

it has changed from the width and the height.
