What is the critical value for a one-tailed (right) hypothesis test of a population mean, when the population standard deviation is known, in which a null hypothesis is tested at the 10% level of significance based on a sample size of 55? Select one: O a. 1.708 O b. 1.282 O C. -1.645 O d. 1.645To conduct a test of hypothesis regarding the mean of a populationr with a small sample, we need to be able to malce an assumption that: Select one: C' a. a larger computed 1uralue oft will be needed to reject the null hypothesis O b. the region of acceptance will be widerthan for large samples O c. the condenoe interval will be wider than for large samples 0 d. the population is normallyr distributed. In hypothesis testing, what do we call the value that determines when to reject the null hypothesis? Select one: O a. Decision rule O b. Test statistic O c. Alternate hypothesis O d. Critical valueWhat is a Type I error? Select one: O a. The probability of failing to reject a false null hypothesis O b. The probability of rejecting a false null hypothesis O c. Accepting a false alternate hypothesis O d. Rejecting a false alternate hypothesisIn a test ofa population mean, what are the two critical values for a two-tailed teEt with a [1.05 level of Eignicanoe when n i5 large and the population standard deviation i5 known? Select one: D a. Above 1.95 and below 4.95 O b. Above 1.55 and below -1.55 O c. Above 2.58 and below 158 D d. Above 1.00 and below -1.U \fWhat is the significance level? Select one: O a. Probability of failing to reject a false null hypothesis O b. Probability of rejecting a true null hypothesis O c. z-value of 1.96 O d. Beta error
