2. A recent broadcast of a television show had a 20 share, meaning that among 7,000 monitored households with TV sets in use, 27% of them were tuned to this program. Use a 0.01 significance level to test the claim of an advertiser among the households with TV sets in use, less than 25% were tuned into the program. Follow the 8 – step process. STEP 1: ORIGINAL CLAIM: STEP 2: OPPOSITE OF ORIGINAL CLAIM: STEP 3: 1. Null Hypothesis (): 2. Alternative Hypothesis (): STEP 4: Select a significance level of = . STEP 5: Since we are testing a claim about a we will use a distribution. STEP 6: Calculate the test statistic to 2 decimal places: STEP 7: 1. Find the p - value to 4 decimal places. Since this test is tailed, the p- value is equal to the area to the of the test statistic. p- value =. Now compare your p– value from above to the significance level: p -value. Since the p – value is LESS / GREATER than

To test the fairness of law enforcement in its area, a local citizens group wanted to know whether women and men are unequally likely to get speeding tickets. 400 randomly selected adults were phoned and asked whether or not they had been cited for speeding in the last year. using the results in the following table and a 0.10 level of significance Men ticket =35, Men not ticketed= 144 women ticketed= 22, women not ticketed = 199 Compute the test statistic
US Universities found that 72% of people are concerned about the possibility that their personal records could be stolen over the internet. If a random sample of 300 college students at a Midwestern university were taken and 228 of them were concerned about the possibility that their personal records could be stolen over the Internet, could you conclude at the 0.025 level of significance that a higher proportion of the university’s college students are concerned about Internet theft than the public at large? Report the p-value for this test. Z0.025 = 1.96
A random sample of 1100 potential voters was randomly divided into 2 groups. Group 1: 500 potential voters; no registration reminders sent; 248 registered to vote Group 2: 600 potential voters; registration reminders sent; 332 registered to vote Do these data support the claim that the proportion of voters who registered was greater in the group that received reminders than in the group that did not? Use a 1% level of significance.
In a previous poll, 38% of adults with children under the age of 18 reported that their family ate dinner together seven nights. suppose that, in a more recent poll, 399 of 1099 adults with children under the age of 18 reported that their family ate dinner together seven nights a week. is there sufficient evidence that the proportion of families with children under the age of 18 who eat diner together seven nights a week has decreased? use the a=0.05 significance level
A study, which randomly surveyed 3,700 households and drew on this information from the IRS, found that 79% of households have conducted at least one IRA rollover from an employer-sponsored retirement plan. Suppose a recent random sample of 90 households in a certain county was taken and respondents were asked whether they had ever funded an IRA account with a rollover from an employer-sponsored retirement plan. Based on the sample data below, can you conclude at the 0.10 level of significance that the proportion of households in the county that have funded an IRA with a rollover is different from the proportion for all households reported in the study? 77 respondents said they had funded an account; 13 respondents said they had not
In a controlled laboratory experiment, scientists at the University of Minnesota discovered that 25% of a certain strain of rats subjected to a 20% coffee bean diet and then force-fed a powerful cancer-causing chemical later developed cancerous tumors. Would we have reason to believe that the proportion of rats developing tumors when subjected to this diet has increased if the experiment were repeated and 16 of 48 rats developed tumors? Use a 0.05 level of significance.
In the previous year, 40% of women over the age of fifty had regularly scheduled mammograms. Following last year's test, a campaign was initiated to encourage women to be tested regularly. This year, a cancer research group surveys a random sample of 450 women, and 195 respond affirmatively. With a 5% significance level, test to see if the campaign was effective. What is the decision rule? Question 9 options: Reject H0 if the p-value > 0.05. Reject H0 if the p-value < 0.05. Accept HA if the p-value > 0.05. Reject HA if the p-value < 0.05. None of these. Reject H0 if the p-value ≠ 0.05.
In a random sample of soldiers who fought in the Battle of Preston, 774 soldiers were from the New Model Army, and 226 were from the Royalist Army. Use a 0.05 significance level to test the claim that fewer than one quarter of the soldiers were Royalist.
