The parameter v for the q-curve in a Tukey multiple comparison equals one of the degrees of freedom for the F-curve in a one-way ANOVA. Which one?
A doctor's office believes the number of flu cases is decreasing. The doctor's office would like to test the claim that the average number of flu cases per day at the doctor's office is under 6 cases. Using the computed test statistic of −1.90 and the critical value of −1.28, is there enough evidence for the doctor's office to reject the null hypothesis? Use the graph below to interpret the critical value. First select the appropriate test type (left-, right-, or two-tailed), then plot the points along the x-axis (for the critical value and test statistic), and use them to choose the appropriate interpretation. powered by $$z=−0.62 Rejection region Move the blue dot to choose the appropriate test Test Statistic 1.24 Select the correct answer below: Yes. There is sufficient evidence for the doctor's office to reject the null hypothesis because the critical valuefalls in the rejection region. No. There is NOT sufficient evidence for the doctor's office to reject the null hypothesis…
A construction firm claims that security cameras are installed in 50% of properties being constructed today in Tokyo. Would you agree with this claim if a random survey of new homes in this town showed that 100 out of 150 had security cameras installed? Use a 0.10 level of significance. This problem is a test on what population parameter? What is the null and alternative hypothesis? What are the Significance level and Type of test? What is the Critical Value? What is the Standard test statistic? What is the Statistical Decision in statement form?
A random sample of 170 donations at a certain blood bank reveals that 84 were Type A blood. Does this suggest that the actual percentage of Type A donations differs from 45%, of the population having Type A blood? A. State H0 and Ha B. Test the hypothesis using the P-Value approach at a significance level of 3%, and express your decision. C Based on the given data, determine the extreme value without rejecting the H0.
In a sample of 1050 adults, it was found that 52% are registered to vote in their state. Use a 0.05 significance level to test the claim that less than 50% of all adults are registered to vote in their state.a. Find the test statistic.b. Find the critical value.c. Find the p-value.d. What is the conclusion about the null hypothesis (reject or fail to reject)?e. What is the final conclusion in nontechnical terms?
In a leg ulcer trial, time to complete ulcer healing (weeks) between intervention and control groups were measured and compared.The researcher wishes to know if there is any difference between the average time taken for complete healing for both groups. P-value computed for Kolmogorov-Smirnov test is less than α = 0.05. Which type of statistical test should the researcher use? 1. Kruskal Wallis test2. Mann-Whitney U test3. Independent T-test4. One-way ANOVA
A professional racing team is holding tryouts at its test track. The team requires its drivers to have an average lap time of at most 133 seconds at its test track. The team will use a one sample z-test of significance to determine if they should hire a new driver. Using the P-value you computed in the previous problem, determine if the team has significant evidence (at level 0.05) that this driver should not join the team. a. Yes, the data is significant at level 0.05, so we reject H0, which assumed the driver had the needed average lap time. b. No, the data is significant at level 0.05, so we fail to reject H0, which assumed the driver had the needed average lap time. c. No, the data is not significant at level 0.05, so we fail to reject H0, which assumed the driver had the needed average lap time. d. Yes, the data is significant at level 0.05, so reject Ha.
A study was done using a treatment group and a placebo group. The results are shown in the table. Assume that the two samples are independent sample random samples selected from normally distibuted populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.01 significance level for both parts. Test the claim that the two samples are from populations with the same mean. What are the null and alternative hypotheses?The test statistic, t, is __?The P value is __?State a conclusion for the test Construct a confidence interval suitable for testing the claim that the two samples are from populations with the same mean.
An agriculture company wants to determine if a new fertilizer has a significant effect on crop yields. The null hypothesis is that the fertilizer has no effect on crop yields, meaning that the average yield with the fertilizer is equal to the average yield without the fertilizer. The company conducts an ANOVA test and obtains an F-statistic of 3.2 and a numerator degrees of freedom of 3 and denominator degrees of freedom of 20. What is the p-value of the hypothesis test?
Hauz of Gaz claims that more than two-thirds of the houses in a certain subdivision use their brand. Is there a reason to doubt this claim if 25 out of a random sample of 40 houses in the subdivision use the company's brand? Test the claim at 0.01 level of significance. What is the value of the test statistic? (a) 0.6053 (b) 0.6503 (c) -0.6053 (d) -0.6503 Based on the result on the comparison between critical and computed value, what can be concluded? (a) There is enough evidence to reject the claim that more than two-thirds of the houses in the subdivision use Hauz of Gaz brand (b) There is not enough evidence to reject the claim that more than two-thirds of the houses in the subdivision use Hauz of Gaz brand (c) Accept the null hypothesis (d) The given information is not enough to make any conclusion
