QUESTION 1 Annual per capita consumption of milk is 21.5 galons with a standard deviation of 4.8 galons. Being from the Midwest, you believe mik consumption is higher there and wish to support your opinion A sample of 30 individuals from the Midwestern town of Webster City showed a sample mean annual consumption of 24.1 galons Which hypotheses can be used to determine whether the mean annual consumption in Webster City is higher than the national mean?

Calculate the estimated standard error for the case where the sample standard deviation is 25 and the sample size 137. Answer to three decimal places if necessary, you may round up or down.

the height of American men is normally distributed with a mean of 70 in and a standard deviation of 3 in. what are the heights in inches that define the most extreme 8% of the population of American men?

Humerus bones from the same species of animal have approximately the same length-to-width ratios. It is known that Species A has a mean ratio of 5.9. Suppose that 100 fossil humerus bones were unearthed at a site where Species A is known to have flourished. (We assume that all bones are from the same species.) The length-to-width ratios of these bones have a sample mean 5.6 and sample standard deviation 0.25.   Can we conclude that the mean ratio of these bones is significantly smaller than those of Species A? Test with a 0.01 significance level.   What is the standard error?

Historically, the mean age of all Memphis residents has been 40 years.  You believe this has changed.  You take a random sample of 130 Memphis residents and find that their mean age is 36 years with a standard deviation of 17 years.  Can you conclude that the mean age of all Memphis residents has changed from 40 years. For the hypothesis testing scenario above, compute the test statistic. For the hypothesis testing scenario above, you conclude that the mean age of all Memphis residents has changed from 40 years at the 0.05 significance level.  Compute the 95% confidence interval to estimate the mean age of all Memphis residents.
