Problem
• Find Tα for a confidence interval (C.I.) of 95%, n = 18.
• Find Zα for a C.I. of 92%, n = any value.
• Determine the sample size necessary to estimate "p", the population proportion, for the following information. E = 0.02, p = 0.40, and the confidence level is 96%.3.) Determine the sample size necessary to estimate "p", the population proportion, for the following information: E = 0.05, p = 0.55, and the confidence level is 90%.4. Given "n" = 12, x¯ = 319.7, "s" = 9.104, compute a 99% C.I. for μ.5. Given σ = 36, E = 5, C.I. = 93%, compute the appropriate size necessary to estimate μ.6. Determine the sample size necessary to estimate "p", the population proportion, for the following info: E= 0.06, a C.I. of 85%, and a p and q which are unknown.
The response should include a reference list. Using double-space, Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
