a. Perform a hypothesis test to verify or deny with 90% certainty the claim that the average number of acres in PA state parks is less than 2000 acres. A random sample of five such parks has these acreages: 959, 1187, 493, 6249, 541. State a statistically appropriate conclusion.

b. Approximate the p-value.

c. Verify or deny with 95% certainty the claim that the average number of acres in PA state parks is less than 2000 acres. A random sample of five such parks has these acreages: 959, 1187, 493, 6249, 541

2. Perform a hypothesis test, then make a conclusion about the claim: A consumer research organization states that the mean time a US adult spends on their computer per day is more than 5.2 hrs. You want to test this claim. You find that a random sample of 20 US adults spend a mean of 5.5 hrs on their computers per day. Assume the population standard deviation is 1.1 hrs. At ? = .02, can you support the research organization’s...

Test the claim that the average financial aid award at MATC is $2000 or less. A sample of100 MATC students is randoml selectedy, and the sample has an average of $1800. Test the claim at the α = 5% significance level. Assume the population has a standard deviation of $300. State the null and alternative hypotheses. ( b) Draw an appropriate distribution curve and label the critical value(s) and shade the critical region(s). c) Determine the test value and label...

Part 1 Hypothesis Test and Confidence Interval from 1 sample Test ONE claim about a population parameter by collecting your own data or using our class survey data. Include your written claim, hypothesis in both symbolic and written form, relevant statistics (such as sample means, proportions etc.), test statistic, p-value (or critical value), conclusion, and interpretation of your conclusion in the context of your claim. Use a 0.05 significance level. You will also construct a 95% confidence interval estimate of...

You wish to test the claim that the average IQ score is less than 100 at the .005 significance level. You determine the hypotheses are: Ho: μ=100 H1:μ<100 You take a simple random sample of 76 individuals and find the mean IQ score is 95.5, with a standard deviation of 15.1. Let's consider testing this hypothesis two ways: once with assuming the population standard deviation is not known and once with assuming that it is known. Round to three decimal...

You will perform a Two Sample Hypothesis Test for Proportions. For the Hypothesis Test, make sure to report the following steps: Identify the null hypothesis, Ho, and the alternative hypothesis, Ha. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Find the critical value(s) and identify the rejection region(s). Find the appropriate standardized test statistic. If convenient, use technology. Decide whether to reject or fail to reject the null hypothesis. Interpret the decision in the context of the original...
