- A study found that 13% of Americans have seen or sensed the presence of an angel. A contingent doubts that the percent is really that high. It conducts its own survey. Out of 76 Americans surveyed, only two had seen or sensed the presence of an angel. As a result of the contingent's survey, would you agree with the study? Will you reject the null hypothesis or not?A credit card company claims that the mean credit card debt for individuals is greater than $5,100. You want to test this claim. You find that a random sample of 32 cardholders has a mean credit card balance of $5,242 and a standard deviation of $575. At a = 0.01, can you support the claim? Complete parts (a) through (d) below. Assume the population is normally distributed. (a) Write the claim mathematically and identify Ho and H2. Which of the following correctly states H, and H,? O A. Ho: µ> $5,100 Ha: us $5,100 В. Но: и- $5,100 Hai µ > $5,100 С. Но: 3 $5,100 Ha: u# $5,100 O D.

(c) Write the alternate hypothesis, if the editor wants to prove that the actual miles per gallon is simply different from what's being claimed.Consider the following statements about hypothesis testing: (i) Reject Ho. Evidence proves support for Ha. (ii) Fail to reject Ho. Evidence disproves support for Ha. (iii) Accept Ho. Evidence proves support for Ho.
