You take a simple random sample of 22 adults in your community and find that they average 4.3 pounds with a standard deviation of 1.4 pounds. Suppose you know the amount of waste generated per day follows a normal distribution. Test at .05 significance. Round to the fourth as needed We can work this problem because: SRS is given and waste generated follows a normal distribution | Ho: H 5 HA:H 5 Test Statistic: P-value: FSA Did something significant happen? |Significance Happened V V Select the Decision Rule: Reject the Null D21 There is vv of enough evidence to conclude + the mean amount of waste generated per adult in your community is less than the national average of 5 pounds per day v Question Help: Message instructor O Submit QuestionEducation D2L Homepage - Walters State Comm X M MyOpenMath X * Course Hero * + X C https://www.myopenmath.com/assess2/?cid=171756&aid=12206346#/skip/8 . . . The blue catfish (Ictalurus Furcatus) is the largest species of North American catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to American Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds. Use the data below, which represents the summary statistics for 44 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds. n = 44; I = 40.32 pounds; $ = 2.47 pounds a) Identify the null and alternative hypotheses? Ho: ? H1: ? v b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? Oleft-tailed O right-tailed O two-tailed FSA c) Identify the appropriate significance level. D21 d) Calculate your test statistic. Write the result below, and be sure to round your final answer to two + decimal places. e) Calculate your p-value. Write the result below, and be sure to round your final answer to four decimal places. OStep by Step Solution
