OBFW PublishersA state's Division of Motor Vehicles (DMV) claims that 60% of all teens pass their driving test on the first attempt. Aninvestigative reporter examines an SRS of the DMV records for 125 teens; 86 of them passed the test on their first try.A hypothesis test ofHo: P = 0.60Ha:p # 0.60where p = the true proportion of teens who pass their driving test on the first attempt using a = 0.05 gives a P-value of 0.0444.A 95% confidence interval for the true proportion of teens who pass the driving test on the first attempt is 0.607 to 0.769.Which is the following statements is not true with regards to the 95% confidence interval provided and the result of thehypothesis test?OA two-sided test only allows us to reject (or fail to reject) a hypothesized value for a particular population parameter.The value 0.60 is not a plausible value because it falls outside the 95% confidence interval.The 95% confidence interval provided gives an approximate set of po's that would not be rejected by a two-sided test atthe a = 0.05 significance level.Based upon the confidence interval we would reject p = 0.60 at the a = 0.05 significance level.All of the statements are true.

The question is about confidence interval.Given : Null and alternative hypotheses :Confidence…

A USA Today article claims that the proportion of people who believe global warming is a serious issue is 0.63, but given the number of people you've talked to about this same issue, you believe it is less than 0.63. The hypotheses for this test are Null Hypothesis: p ≥ 0.63, Alternative Hypothesis: p < 0.63. If you randomly sample 20 people and 12 of them believe that global warming is a serious issue, what is your test statistic and p-value? Question 3 options: 1) Test Statistic: 0.278, P-Value: 0.391 2) Test Statistic: 0.278, P-Value: 0.609 3) Test Statistic: -0.278, P-Value: 0.782 4) Test Statistic: -0.278, P-Value: 0.391 5) Test Statistic: -0.278, P-Value: 0.609

When the 2000 GSS asked whether human beings developed from earlier species of animals, 53.8% of 1095 respondents answered that this was probably or definitely not true. Question: What is the null and alternative hypothesis for this question
A researcher believes that 52.5% 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: a) Find the mean of p: b)Find the standard deviation of p: c) Compute an approximation for P(p ≥ 0.525), which is the probability that there will be 52.5% or more people with IQ scores over 100 in the sample. Round your answer to four decimal places.
A school reports that 89% of its graduates get jobs within one year. You take a random sample of 53 graduates, of whom 43 got a job within one year. Is this enough evidence to show that a significantly different percent of graduates get jobs than advertised by the school? (Use a=0.10)
Sleep apnea is a condition in which the sufferers stop breathing momentarily while they are asleep. This condition results in lack of sleep and extreme fatigue during waking hours. A current estimate is that 9.7 million out of the 312.7million Americans suffer from sleep apnea, or approximately 3.1%A safety commission is concerned about the percentage of commercial truck drivers who suffer from sleep apnea. They do not have any reason to believe that it would be higher or lower than the population’s percentage. To test the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 3.1%, a simple random sample of 406commercial truck drivers is examined by a medical expert, who concludes that 55 suffer from sleep apnea. Does this evidence support the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 3.1%?Use a 0.05 level of significance. Step 3 of 3 : Draw a conclusion and interpret the decision.
A question in a poll taken in 2007 asked, "Do you think the penalties for underage drinking should be made more strict, less strict, or remain the same?" The sample proportion that responded "more strict" was 0.61 (61%). This result will be used to estimate the proportion of all adults in the United States who think that penalties for underage drinking should be more strict. The sample consisted of n = 500 randomly selected adults in the United States Calculate a 95% confidence interval that estimates the population proportion who think that penalties for underage drinking should be more strict. (Round your answers to three decimal places.)
We have Ho : p = .4 and H1: p > .4. You run 50 experiments and find that the sample proportion is .42. Use alpha = .01 to test the hypothesis.
Babies and younger boys are more likely to be diagnosed with peanut allergies. To test this claim a group of researchers tested the allergies among a group of boys and girls aged below 18 years. A total of 540 kids were selected randomly and asked to eat a small amount of peanut. Group n x Boys 280 120 Girls 260 90 Do boys have a higher chance to be diagnosed with a peanut allergy? Calculate the test statistic. Calculate p-value.
A manufacturer claims that 10% of women using the "pill" suffer from side effects. The Federal Drug Administration (FDA) believes that the manufacturer's claim is too low and decides to test the manufacturer's claim at a 5 %. A random sample of 900 women who use the manufacturer's pill shows that 103 suffer side effects. The p-value of this test is: O a. 0.1144 Ob. 0.0644 O C. 0.1000 Od. 0.0743 e. 0.0144
Español According to previous studies, 10% of the U.S. population is left-handed. Not knowing this, a high school student claims that the percentage of left-handed people in the U.S. is 12%. The student is going to take a random sample of 900 people in the U.S. to try to gather evidence to support the claim. Let p be the proportion of left-handed people in the sample. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p. 0.12 (b) Find the standard deviation of p. X 5 (c) Compute an approximation for P(p≤0.12), which is the probability that there will be 12% or fewer left-handed people in the sample. Round your answer to four decimal places. A 27
A reader wrote in to the “Ask Marilyn” column in Parade magazine to say that his grandfather told him that in three-quarters of all baseball games, the winning team scores more runs in one inning than the losing team scores in the entire game. (This phenomenon is known as a “big bang.”) Marilyn responded that this proportion seemed too high to be believable. Let p be the proportion of all major-league baseball games in which a “big bang” occurs. To investigate this claim, we randomly selected one week of the 2006 major-league baseball season, which turned out to be July 31-August 6, 2006. Then we examined the 95games played that week to determine which had a big bang and which did not. Of the95 games in our sample, 47 contained a big bang. Use a two-sided alternative, state the null and alternative hypothesis (in symbols and in words) for testing Marilyn’s claim. 7. Determine the test statistic and p-value. 8. What conclusion would you draw concerning Marilyn’s conjecture using the…
