Question 1 Would you accept the alternative hypothesis {in a left tail test}, if the probability of Type | Error is 5% and The p-Value is equal to 110922? 0 No 0 Yes Q Depends on the condence interval 0 This is subject to management approval 0 This is subject to the needs of marketing goals Question 2 What do you do, if the p-value in your hypothesis test is equal to 0.0002? O The decision depends on the probability of Type | Error we are ready to tolerate O Do not reject the null hypothesis O Reject the null hypothesis O Reformulate the alternative hypothesis O Select the level of significance in order to accept the alternative hypothesisQuestion 3 1 points Save Answer lConsiderthe following hypotheses statement for the average life span of a laptop battery: H0 : p = 4 1fears, Ha : p i :1 years. lfa sample of laptop batteries, consisting of 60 items, showed the sample average lifespan of 4.1 years, and the standard deviation of the cost ofall such computer parts in the population is [1.3 years, what is the pvalue for the test statistic? Use Excel and round your answerto II decimal places. QuEStl on 4 Considerthe following hypotheses statement for the average cost of a computer part: Hi] : p S 56, Ha : u > 56. lfa sample of computer parts consisting of it] items, showed the sample average cost of 58, and the standard deviation of the cost ofall such computer parts in the population is 6, what is the pvalue forthe test statistic? Use Excel and round your answer to 4 decimal places. Find The sum of squares due to regression, if the sum of squares due to error is 5,328.12 and the total sum of squares is 15,931.51. Round your answerta 2 decimals. Quesuon 6 Alpha Corp. believed that theircompetitors, Betta Corp., are not delivering goods as fast as they claimed. Alp ha decided to test this hypothesis. Following the hypothesis testing, Alp ha found that their suspicion was not supported, and accepted the hypothesis that Betta are fast as they claim. However, the fact of the matter was that Betta was slower than they claimed. Alp ha Corp. made the following error: 0 Type II error 0 Mixedtype error C) An example of 90% poorjudgement C) An example of below 911% acceptablejudgement C) Type I error QuEStl on 7 Researchers used the leastsquares method to study the relationship between the length of time (in munues) a commercial was shown during a week and the number of products purchased. As one of the researchers, use the simple linear regresssion equation to nd the predicted number of products purchased ifthe commercial is sh own for 2.5? during the next week. It is known that the yintercept of the estimated regression line is T0131 the slope of the estimated regression line is 1.95. Round your answer to 2 decimals (do not round to a whole number. if the answer is not a whole number). For example, for 45.82 products, enter 45.82, not 46. Question 3 2 points Save Answer Researchers used the simple linear regression model to studyr the relationship between social media screen time during a week and endofweek quiz results. As one of the researchers, nd the predicted quiz score ifa student spends 2.15 hours during the next week using social media. Use the data in the table below to build the estimated regression equation and then use this equation to nd the predicted quiz score: Social media weekly time, hours Round your answer to 2 decimals.
