A sample of 17 patients in a hospital had these hemoglobin readings 112 120 98 55 71 35 99 142 64 150 150 55 100 132 20 70 93 find a 95% confidence interval for the hemoglobin reading for all the patienta in the hospital

The 95% confidence interval for the hemoglobin reading for all the patients in the hospital is (72, 112).

Step-by-step explanation:

The (1 - α)% confidence interval for the population mean, when the population standard deviation is not provided is:

The data provided is:

S = {112, 120, 98, 55, 71, 35, 99, 142, 64, 150, 150, 55, 100, 132, 20, 70, 93}

Compute the sample mean and sample standard deviation as follows:

The critical value of t for 95% confidence level and n - 1 = 16 degrees of freedom is:

*Use a t-table.

Compute the 95% confidence interval for the hemoglobin reading for all the patients in the hospital as follows:

Thus, the 95% confidence interval for the hemoglobin reading for all the patients in the hospital is (72, 112).

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

imma say 16%. sorry if its wrong. i'm doing the same stuff right now
