P-values In Exercises 17–20, do the following:
a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed.
b. Find the P- value. (See Figure 8-3 on page 364.)
c. Using a significance level of α = 0.05, should we reject H0 or should we fail to reject H0?
The test statistic of z = 1.00 is obtained when testing the claim that p > 0.3.
Perform the hypothesis test at 5% significance level using the p-value approach
x=33, s=10, n=24, H0: u=26, Ha: u>26
What is the test statistic, p value, and conclusion for the hypothesis
Work
Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion.
A person drilled a hole in a die and filled it with a lead weight, then proceeded to roll it 200 times. Here are the observed frequencies for the outcomes of 1, 2, 3, 4, 5, and 6, respectively: 27, 29, 50, 41, 29, 24. Use a 0.10 significance
level to test the claim that the outcomes are not equally likely. Does it appear that the loaded die behaves differently than a fair die?

The test statistic is.
(Round to three decimal places as needed.)
The critical value is
(Round to three decimal places as needed.)
State the conclusion.
Ho- There
sufficient evidence to support the claim that the outcomes are not equally likely. The outcomes
to be equally likely, so the loaded die
to behave differently from a
fair die.

Cadmium, a heavy metal, is toxic to ani-mals. Mushrooms, however, are able to absorb and accumulate cad-mium at high concentrations. The Czech and Slovak governments have set a safety limit for cadmium in dry vegetables at 0.5 part per million (ppm). M. Melgar et al. measured the cadmium levels in a random sample of the edible mushroom Boletus pinicola and pub-lished the results in the paper “Influence of Some Factors in Toxi-city and Accumulation of Cd from Edible Wild Macrofungi in NW Spain” (Journal ofEnvironmental Science and Health, Vol. B33(4), pp. 439–455).
