If, in a one-tail hypothesis test where H0 is only rejected in the upper tail, the p-value=0.6792 and ZSTAT=−0.47,what is the statistical decision if the null hypothesis is tested at the 0.07 level of significance? What is the statistical decision? Since the p-value is Less than or Greater than or equal to a= , Reject , Do not reject H0.
Suppose 26 of 200 tires of brand A failed to last 30000 miles, whereas the corresponding figure for 200 tires of brands B was 32. Test the null hypothesis that there is no difference in the quality of the two kinds of tires at the α=:05 significance level.
A two-sample t-test for a difference in means was conducted to investigate whether there is a statistically significant difference in the average amount of fat found in low-fat yogurt and the average amount of fat found in nonfat yogurt. With all conditions for inference met, the test produced a test statistic of t=2.201 and a p-value of 0.027. Based on the p-value and a significance level of α=0.05, which of the following is the correct conclusion? Reject the null hypothesis because p<α. The difference in the average amount of fat found in low-fat and nonfat yogurt is not statistically significant. A Reject the null hypothesis because p<α. The difference in the average amount of fat found in low-fat and nonfat yogurt is statistically significant. B Fail to reject the null hypothesis because p<α. The difference in the average amount of fat found in low-fat and nonfat yogurt is not statistically significant. C Fail to reject the null…
In a hypothesis test with hypotheses H0 :pless than or greater than 0.58 and H1 >0.58 , a random sample of size 1,165 produced a sample proportion of 0.6160. The test is to be made at the 2.5% significance level. What is the value of the test statistic, z, rounded to three decimal places?
Also, using α = .05, run a two-tail t-test for one sample to test Ho: µ=283 for the 2009 scores. Report the t-obt, df, and p-values. Would you reject the null hypothesis that the 2009 scores come from a population with average 283? If this is the case, does it come from a population from larger or smaller average?
To evaluate the effect of a treatment, a sample ofn = 8 is obtained from a population with a mean of m =50, and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be M = 55. Assuming that the sample variance is s2 =32, use a two-tailed hypothesis test with a = .05 to determine whether the treatment effect is significant and compute both Cohen’s d and r2 to measure effect size. Assuming that the sample variance is s2 = 72, repeat the test and compute both measures of effect size. Comparing your answers for parts a and b, how does the variability of the scores in the sample influence the outcome of a hypothesis test and measures of effect size?
A sample poll of 500 voters from Michigan and 300 voters from Wisconsin showed that 51% and 49% is in favor of Donald Trump, respectively. At a significance level of 0.05, and using two-tailed test: a.) What should be the good hypotheses? b.) What is the t-value/z-value? c.) Is there is a difference between the two states?
One sample has n = 17 with SS = 1646, and a second sample has n = 17 with SS = 1710. If the sample mean difference is 6 points, is this enough to reject the null hypothesis and conclude that there is a significant difference for a two-tailed test at the 0.10 level?(Use/round to 3 decimal places.)What is the t-critical? =what is the t? =
A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 418 gram setting. Is there sufficient evidence at the 0.05 level that the bags are underfilled or overfilled? Assume the population is normally distributed. State the null and alternative hypotheses for the above scenario. H0: Ha:
According to a certain government agency for a large country, the proportion of fatal traffic accidents in the country in which the driver had a positive blood alcohol concentration (BAC) is 0.36. Suppose a random sample of 110 traffic fatalities in a certain region results in 49 that involved a positive BAC. Does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country at the α=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 conclusion? 0.0747 None of these. Reject H0 and conclude that the campaign was effective. Fail to reject H0 and conclude that the campaign was effective. Fail to reject H0 and conclude that the campaign was not effective.
A researcher administers a treatment to a sample from a population with a mean of m=50. If the treatment is expected to increase scores and a one-tailed test is used to evaluate the treatment effect, the the null hypothesis states that m=40. True or false?
