Members of the city council want to know if a majority of city residents supports a 1% increase in the sales tax to fund road repairs. To investigate, they survey a random sample of 300 city residents and use the results to test the following hypotheses: Ho: p = 0.50 H p> 0.50 where p is the proportion of all city residents who support a 1% increase in the sales tax to fund road repairs. Given that P-value = 0.18, which of the following would be the most appropriate conclusion? Because the P-value is large, we reject Ho. We have convincing evidence that at most 50% of city residents support the tax increase. Because the P-value is large, we fail to reject Ho. We have convincing evidence that more than 50% of city residents support the tax increase. O Because the P-value is large, we reject Ho. We have convincing evidence that more than 50% of city residents support the tax increase. Because the P-value is large, we fail to reject Họ. Ywe do not have convincing evidence that more than 50% of city residents support the tax increase. O Because the P-value is large, we reject Ho. We have convincing evidence that at most 50% of city residents supnort the tax increase.

Members of the city council want to know if a majority of city residents supports a 1% increase in the sales tax to fund road repairs. To investigate, they survey a random sample of 300 city residents and use the results to test the following hypotheses: Họ: p = 0.50 Hip > 0.50 where pis the proportion of all city residents who support a 1% increase in the sales tax to fund road repairs. In the sample, p = 158/300 = 0.527. The resulting P-value is 0.18. What is the correct interpretation of this P-value? Assuming that 50% of residents support the tax increase, there is an 18% probability that the sample proportion would be 0.527 or greater by chance alone. There is an 18% chance that the majority of residents supports the tax increase. Assuming that 50% of residents support the tax increase, there is an 18% chance that the null hypothesis is true by chance alone. Assuming that more than 50% of residents support the tax increase, there is an 18% probability that the sample proportion…
(c) Calculate the test statistic. d) Decide whether to reject or fail to reject the null hypothesis. Then interpret the decision in the context of the original claim.
A researcher belleves that 52% of people who grew up as the only child have an IQ score over 100. However, unknown to the researcher, this figure is actually 50%, which is the same as in the general population. To attempt to find evidence for the claim, the researcher is going to take a random sample of 400 people who grew up as the only child. Let p be the proportion of people in the sample with an IQ score above 100. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p. (b) Find the standard deviation of p. (c) Compute an approximation for P(p 20.52), which is the probability that there will be 52% or more people with IQ Scores over 100 in the sample. Round your answer to four decimal places. 2022 acer
It has been claimed that at UCLA at least 40% of the students live on campus. In a random sample of 250 students, 90 were found to live on campus. Does the evidence support the claim at = .01?
A survey by Men’s Health magazine stated that 14% of men said they used exercise to reduce stress. Could this be valid, or is it actually less than what the magazine claims? A random sample of 100 men was selected, and 10 said that they used exercise to relieve stress. If a=0.10, test a hypothesis and state your conclusion in context.
A polling company conducted a hypothesis test to see if people are happy with the government, and they did so by conducting a two-sided test for a population ratio. population proportion). They calculated the value of the test statistic and found that it wasz=2.1 .What is the p-value of the test?
According to a recent study in New York, 15% of shoppers are unfairly being charged sales tax in non-taxable items. Mr. Hypothesis feels this proportion is too low. He tests his belief by conducting a survey of 200 random shoppers. Which of the following would be the alternate hypothesis? a. The percent of shoppers unfairly being charged sales tax on non-taxable items < .15 b. The percent of shoppers unfairly being charged sales tax on non-taxable items > .15 c. The percent of shoppers unfairly being charged sales tax on non-taxable items = .15
Life on Other Planets Forty-five percent of people believe that there is life on other planets in the universe. A scientist does not agree with this finding. He surveyed 110 randomly selected individuals and found 66 believed that there is life on other planets. At α=0.05, is there sufficient evidence to conclude that the percentage differs from 45? Use the P-value method with a graphing calculator. State the hypotheses and identify the claim with the correct hypothesis.

Let p1 be the proportion of residents in Country A coping with depression, and let p2 be the proportion of residents in Country B coping with depression. What is the null hypothesis for a test to determine whether Country A has a greater proportion of residents coping with depression than Country B?

For example before the pandemic, students from the 7:00am class reported that they sleep on average 6 hours. However, report shows that it is uncertain whether students sleep longer than six hours or less than 6 hours. Someone consulted you on how to provide statistical evidence whether the students sleep less than 6 hours or more than 6 hours. what test will you use to investigate the problem above?
In a fishing lodge brochure, the lodge advertises that 75% of its guests catch northern pike over 20 pounds. Suppose that last summer 59 out of a random sample of 85 guests did, in fact, catch northern pike weighing over 20 pounds. Does this indicate that the population proportion of guests who catch pike over 20 pounds is different from 75% (either higher or lower)? Use a = 0.05. (a) What is the level of significance? State the null and alternate hypotheses. O Ho: p = 0.75; H1: p 0.75 (b) What sampling distribution will you use? O The Student's t, since np 5 and ng > 5. O The standard normal, since np 5 and nq > 5. What is the value of the sample test statistic? (Round your answer to two decimal places.) (c) Find the P-value of the test statistic.
