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.

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
