The following table gives projections of the U. S. population from 2000 to 2100. a) Find a linear function that models the data (the equation of best fit) with x equal to the number of years after 2000 and f(x) equal to the population in millions.

Find f(65) and state what it means.
Find the slope of the line. What does it mean in the context of the problem?

The null and alternate hypotheses are: h0: μ1 ≤ μ2 h1: μ1 > μ2 a random sample of 22 items from the first population showed a mean of 113 and a standard deviation of 12. a sample of 16 items for the second population showed a mean of 99 and a standard deviation of 6. use the 0.01 significant level. find the degrees of freedom for unequal variance test. (round down your answer to the nearest whole number.) state the decision rule for 0.010 significance level. (round your answer to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? use the 0.01 significance level.
