The following sample data are from a normal population: 10, 8, 12, 16, 13, 11, 6, 4. a. What is the point estimate of the population mean?

b. What is the point estimate of the population standard deviation (to 3 decimals)?

c. With 95% confidence, what is the margin of error for the estimation of the population mean (to 1 decimal)?

d. What is the 95% confidence interval for the population mean (to 1 decimal)?

360/29

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
