Tree-ring dates were used extensively in archaeological studies at Burnt Mesa Pueblo. At one site on the mesa, tree-ring dates (for many samples) gave a mean date of µ1 =
year 1256 with standard deviation o1 = 34 years. At a second, removed site, the tree-ring dates gave a mean of µ2 = year 1107 with standard deviation o2 = 35 years.
Assume that both sites had dates that were approximately normally distributed. In the first area, an object was found and dated as x1 = year 1209. In the second area,
another object was found and dated as x2 = year 1237.

Feeling that this figure is too high and the average cost of services to customers is less than $90 per month, we question a random sample of 14 customers. Our sample yields a mean cost of $85 and a standard deviation of $10. Test at the 0.10 significance level. Assume that such costs are normally distributed. Show all steps.
QUESTION 5. The English department at Arizona State University measured the vocabularies of its entire undergraduate student body by having each student give definitions of words on 10 selected pages of a dictionary and then multiplying the number of correct definitions by a factor that accounted for the total number of words in that dictionary. The English department concluded that the 44,445 students' vocabularies were normally distributed around mean of 37,500 words with a standard deviation of 8000 words. Based on this data, give the best estimate of how many ASU students had vocabularies between 13,500 and 29,500 words.
Question 25: The weights of newborn children in the United States vary according to the normal distribution with mean 7.5 pounds and standard deviation 1.25 pounds. An article in the The Wall Street Journal claims that the average birth weight is decreasing over time.

Test the claim using a 1% level of significance that the mean weight significantly smaller than the national average of 7.5 pounds. Use the population standard deviation of 1.25 pounds. Give answer to at least 4 decimal places. What are the correct hypotheses? (Select the correct symbols.)
