The National Cancer Institute conducted a 2-year study to determine whether cancer death rates for areas near nuclear power plants are higher than for areas without nuclear facilities. A spokesperson for the Cancer Institute said, "From the data at hand, there was no convincing evidence of any increased risk of death from any of the cancers surveyed due to living near nuclear facilities.” (1 points for each)    Let p denote the proportion of the population in areas near nuclear...

A scientist has read that the mean birth weight, ?, of babies born at full term is 7.4 pounds. The scientist, believing that ? is different from this value, plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 7.1 pounds and the standard deviation to be 1.8 pounds. Based on this information answer the following questions What are the null...

You are interested in the weight gain of the Auburn Freshman. You think that the average weight gain of the Auburn Freshman student is not 15 pounds. You collect a random sample of measurements. The weight gains are (a negative value indicates a weight loss): 9, 19, 10, 18, 14, 11 You may assume for the following questions that the distribution of weight gain is normal. (a) State the appropriate hypothesis test. (This was done before collecting the data) Null...
