Let y be a random variable representing blood glucose level 1 hour after drinking sugar water (after the 12-hour fast). Units are in milligrams per 10 milliliters (mg/10 ml). A random sample of eight adults gave the following information. I need help with Part A, B, and Carrow_forwardData for question on screenshot. For each of the surveys, include the Summary Statistics and your Confidence Level/Alpha. At least 90% Confidence is recommended for all 3. Television Survey: In a recent survey, it was stated that Americans watch television on average four hours per day. Assume that σ = 2. Using your class (or any 20 – 30 people) as the sample, conduct a hypothesis test to determine if the average for students at your school is lower. Do not make up your data. Write your answers in the tables below. Sample Mean Sample Standard Deviation Confidence Level What is your null hypothesis? What is your alternative hypothesis, ?
