QUESTION 8 Mixed Practice Read through the problem below. Then, identify the problem type by stating whether the problem is a "regular" problem or a "CLT" problem. Then identify the direction by stating whether it is a “forwards" or a “backwards" problem. Then, solve the problem. Round standard error vlaues to the nearest thousandth and z-scores to the nearest hundredth whenever necessary. According to values collected from gasbuddy.com in the spring of 2016, the mean price for a gallon of gas in Oneida County was $2.12, with a standard deviation of $0.06. Madina examines a SRS of 32 gas stations, and finds her sample has a mean in the 97th percentile. What was the mean price of gas in Madina's sample, to the nearest cent? Туре: Direction: Only find Pz and oz if the type is "CLT." If the type is "regular," leave this box blank. Hx = Work: Ox = Work: Which image below (A, B, C, or D) looks most similar to the curve you drew? A Z-score: Work/explain: Area on Table: Work/Explain: Final Answer: Work:

HAV is a deformation of the big toe that often requires surgery. Doctors used X-rays to measure the angle (in degrees) of deformity in 38 consecutive patients under the age of 21 who came to a medical center for surgery to correct HAV. The angle is a measure of the seriousness of the deformity. Here are the data. 292216 321828 231529 352322 372249 261623 263328 202530 321933 242138 262230 112023 2124 It is reasonable to regard these patients as a random sample of young patients who require HAV surgery. Given a 95% confidence interval for the mean HAV angle in the population of all such patients, find the following. x (mean) =  s=(standard deviation) =    Confidence Interval:          ° to  °   Conclusion 1) We are 95% confident that the mean HAV angle among such patients is within this interval. 2) We are 95% confident that the mean HAV angle among such patients is outside this interval.     3) The mean HAV angle among such patients will always be outside this interval 95% of…
