- If a binomial experiment has probability p success, then the probability of failure is ____________________. The probability of getting exactly r successes in n trials of this experiment is C(_________, _________)p (1p)In a one-tail hypothesis test where you rejected Ho only in the upper tail, what is the value is Zstat =+2.00?In a one-tail hypothesis test where you reject H0 only in the upper tail, what is the p-value if ZSTAT = +2.00?
- H1: u > uo is an upper tailed hypothesis testTrue or FalseYou conduct a two-tailed hypothesis test and get a test statistic of z = 1.17 and a Pvalue = .2420. If your test had been a left-tailed test the Pvalue would have beenA company selling home furnaces claims that installingtheir new high efficiency furnace will “cut your heating bill in half.” A consumer agency collects data for a ran-dom sample of homes and plots this year’s heating costs with the new furnaces against previous costs with the oldfurnaces. Which are the most appropriate hypotheses totest the company’s claim?A) H0: b = 0, HA: b ≠ 0B) H0: b = 0, HA: b 7 0C) H0: b = 0, HA: b 6 0D) H0: b = 0, HA: b 6 0.5E) H0: b = 0.5, HA: b ≠ 0.5
- In a Chi-square analysis, what condition causes one to reject (fail to accept) the null hypothesis?If your null and alternative hypothesis are:H0:μ=59H0:μ=59H1:μ≠59H1:μ≠59Then the test is: right tailed two tailed left tailedCould you please help me out with this question… Does ivy grow better in areas with more sun versus in shady areas? Formulate one null (H0) and one alternative (H1) hypothesis.
- Find the quantity (deviance) for testing the hypothesis H0 and the pvalue usedA hypothesis test produces a t statistic of t = +2.19. If the researcher is conducting a two-tailed hypothesis test with α = .05, how large does the sample have to be in order to reject the null hypothesis?A. Express the null hypothesis H0 and the alternative hypothesis Ha in notation form in the following scenarios. 1. The mean annual income of workers who are college graduates is greater than Php100,000 a year. 2. The percentage of women who watches sports on TV is not 40% as claimed by a researcher. 3. A random sample of 60 working students was taken in order to determine whether the average age of working students is different from 19 years.
