- I post the questions few times but all times tutors gave the wrong solution, i give them 1 downvote. Don't answer my questions again who already gave me the answer.now i will give them multiple down votes. I also give you the multiple times down votes who will give me the wrong answer for my Statistics questions. Don't reject my question, if you don't know the answer, leave it for other tutors.Please send me answer within 10 min!! I will rate you good for sure!! Please provide an explanation of your solution!!A patient is classified as having gestational diabetes if their average glucose level is above 140 milligrams per deciliter (mg/dl) one hour after a sugary drink is ingested. Rebecca's doctor is concerned that she may suffer from gestational diabetes. There is variation both in the actual glucose level and in the blood test that measures the level. Rebecca's measured glucose level one hour after ingesting the sugary drink varies according to the Normal distribution with μ=140+5 mg/dl and σ=5+1 mg/dl. Using the Central Limit Theorem, determine the probability of Rebecca being diagnosed with gestational diabetes if her glucose level is measured: Once? n=5+2 times n=5+4 times Comment on the relationship between the probabilities observed in (a), (b), and (c). Explain, using concepts from lecture why this occurs and what it means in context.
