Trader Joe’s is a privately held chain of specialty grocery stores in the United States. Starting out as a small chair of convenience stores, it has expanded to over 340 stores as of June 2010 (http://Tradejoe.com). It has developed a reputation as a unique grocery store selling products such as gourmet foods, beer and wine, bread, nuts, cereal, and coffee. On of their best-selling nuts is Raw California Almonds, which are prices at $4.49 for 16 ounces. Since it is impossible to pack exactly 16 ounces in each packet, a researcher has determined that the weight of almonds in each packet is normally distributed with a mean of 16.01 ounces and a standard deviation of 0.08 ounces.Suppose your cereal recipe calls for no less the 48 ounces of almonds. What is the probability that three packets of almonds will meet your requirement? 

A random sample is drawn from a population with mean μ = 66 and a standard deviation σ =5.5Calculate the probability that the sample mean falls between 66 and 68 for n = 36. 

A random sample of size n = 80 is taken from a population with mean μ = -15.2 and standard deviation σ = 5.What is the probability that the sample mean falls between -15 and -14? (Do not round intermediate calculations) 

A random sample of size n = 66 is taken from a population with mean μ = -12.5 and standard deviation σ =6.What is the probability that the sample mean is less than -13? 

A study by Allstate Insurance Co. finds that 82% of teenagers have used cell phones while driving (the Wall Street Journal, May 5, 2010). Suppose a random sample of 100 teen drivers is taken.Calculate the standard error for the sampling distribution of the sample proportion.

True or False:  The sampling distribution of the sample mean is approximately normal based on any given sample size.
