Which value is the best estimate of the mean of the population?

A population is estimated to have a standard deviation of 10. We want to estimate the population mean within 2, with a 95% level of confidence. How large a sample is required? 8. The estimate of the population proportion is to be within plus or minus .05 with a 95% level of confidence. The best estimate of the population proportion is .15.

Step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
