Provide an appropriate response. Use the Standard Normal Table to find the probability. 11) The distribution of cholesterol levels in teenage boys is approximately normal with 170 ando - 30 (Source: U.S. National Center for Health Statistics). Levels above 200 warrant attention. Find the probability that a teenage boy has a cholesterol level greater than 225. A) 0.0718 B) 0.0012 C) 0.0606 D) 0.0336

Decide whether you can use the normal distribution to approximate the binomial distribution. If you can use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot explain why and use the binomial distribution to find the indicated probabilities A survey of adults found that 8% say their favorite sport is auto racing. You randomly select 600 adults and ask them to name their favorite sport. Complete parts (a) through (d). Determine whether a normal...

the bottom three are the same question ^ ^ ^ Find the probability and interpret the results. If convenient, use technology to find the probability. The population mean annual salary for environmental compliance specialists is about $64,500. A random sample of 44 specialists is drawn from this population. What is the probability that the mean salary of the sample is less than $62,000? Assume o = $6.200 The probability that the mean salary of the sample is less than $62,000...
