1. during fiscal year 2004, the mean monthly benefit per person participating in the federal food-stamp program in nebraska was $79.52. due to the poor economy, more people are using this support program to purchase eligible food. a random sample of 15 people using food stamps was obtained. assume the distribution of monthly benefit per person is normal, the population standard deviation is $4.50. the significance level α is 0.05. a hypothesis test is performed to determine if there is enough evidence to suggest the true mean monthly benefit per person has increased? if the true mean monthly benefit per person is $82, find (a) the probability of committing the type i error. (b) the power of the test. (c) the probability of committing the type ii error.

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
