State whether the hypothesis test would involve a left-tailed test, a right-tailedtest or a two-tailed test. Be sure to use the correct symbol (µ, o, or p) for the indicatedparameter. (You might want to look at exercises 5-8 on page 371 in your textbook for guidancehere.)a.) 62% of students feel that they don't get enough sleep, impacting their studies.b.) The mean antler of red deer is less than 73 centimeters.c.) The standard deviation on the exam was 3.9 points.d.) Most students think that their statistics professors are horribly overbearing.e.) The mean wait time at the bank is more than 4.3 minutes.

As due to the honor-code, we are authorized to answer only 3 subparts for each question and that you haven't specified which of the 3 subparts you want the solutions for, the first 3 subparts are being answered for now. Requesting you to re-upload the question stating the remaining subparts for the answers to them with all the required information. Let the proportion of students who feel that they don't get enough sleep, impacting their studies : p =0.62 The hypothesises are given by : H0: p = 0.62 vs H0: p ≠ 0.62 Let the mean antler of red deer : μ = 73 centimeters The hypothesises are given by : H0 : μ = 73 centimeters vs H1 : μ < 73 centimeters H0 : σ = 3.9 points vs H1 : σ ≠ 3.9 points Let the standard deviation of exams : σ = 3.9 points The hypothesises are given by : H0 : σ = 3.9 points vs H1 : σ ≠ 3.9 points
