A Type 1 Error of 0.05 implies that the: Select one: Q a. probability of rejecting the null hypothesis = 5% O b. probability of accepting the null hypothesis = 5% O c. probability of rejecting the null hypothesis when the null is true = 5% Q d. probability of not rejecting the null hypothesis when the alternative hypothesis is true = 5% Il To be able to reject the null hypothesis with a level of significance of 1% requires the following: Select one: Q a. That the bvalue is less than 5% O b. That the test statistic follows a normal distribution 0 c. That the confidence level is less than the level of significance 0 cl. That the test statistic has a probability less than 0.01. Which of the following is true? Select one: Q a. A confidence level of 90% implies that 90% of the data points fall within one standard deviation 0 b. The confidence level indicates the probability of obtaining a value between the lower and upper limit 0 c. A negative probability implies that the random variable is located on the farleft limit 0 d. A 95% confidence level means that 95% of all possible samples include the true population parameter An analyst collected data on quality complaints. A sample of 25 monthly reports indicated a mean of 167 quality complaints. The sample standard deviation is 15. What distribution should be used for hypothesis testing? Select one: Q a. Normal distribution 0 b. We need more information to determine the distribution 0 c. The population distribution 0 d. tdistribution A group of investors have hired you to analyze financial returns in dollar amounts. A sample of 100 small companies resulted in a mean of $158,000. The population standard deviation is known to be $35,000. Calculate the lower limit for a 95% confidence interval of the population mean. Select one: Q a. $123,000 0 b. $124,750 0 c. $151,140 0 d. $4.51
