For each exercise, perform the steps below. (a) Identify the claim and state Ho and H. (b) Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed, and whether to use a z-test, a t-test, or a chi-square test. Explain your reasoning. (c) Choose one of the options. Option 1: Find the critical value(s), identify the rejection region(s), and find the appropriate standardized test statistic. Option 2: Find the appropriate standardized test statistic and the P-value. (d) Decide whether to reject or fail to reject the null hypothesis. (e) Interpret the decision in the context of the original claim. 1. A random sample of 13 $1 Trifecta tickets at a local racetrack paid the following amounts (in dollars and cents). Is there sufficient evidence to conclude that the average Trifecta winnings exceed $50? Use. Assume the variable is normally distributed. 8.90 141.00 72.70 32.40 70.20 48.60 75.50 19.00 15.00 83.00 59.20 190.10 29.10

Directions: Please use all your relevant tables and formulas for
each problem. You are not limited to just these pages (& space).
Use as much as you need. Please show all relevant data, write
all appropriate formulas, draw appropriate diagrams, and
properly state conclusions for each test. You don't need to do
the P-test for any of the questions, just follow your normal
testing procedures. A formula page is given at the very end of
this test, use it as needed.
For each exercise, perform the steps below.
(a) Identify the claim and state Họ and H..
(b) Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed,
and whether to use a z-test, a t-test, or a chi-square test. Explain your reasoning.
(c) Choose one of the options.
Option 1: Find the critical value(s), identify the rejection region(s), and find
the appropriate standardized test statistic.
Option 2: Find the appropriate standardized test statistic and the P-value.
(d) Decide whether to reject or fail to reject the null hypothesis.
(e) Interpret the decision in the context of the original claim.
