1) population mean life span is 75 years. A random sample of 20 notice Honolulu advertisers gave following lifespan in Honolulu residents: 72, 68, 81, 93, 56, 19, 78, 94, 83, 84, 77, 69, 85, 97, 75, 71, 86,47,66, 27 A) use a calculator with sample mean and standard deviation keys to find x and s ( round your answer to two decimal places) X= ____ yr S= _____ yr B) indicate the population mean lifespan for Honolulu residents is less than 75 years? Use a 5% level of significance. What is the level of significance ___ What is the value of the sample test statistics (round your answer to three decimal places) ___ 2) a random sample of 50 binomial trials resulted in 20 successes. Test the claim that the population does not equal 0.50. Use a level of significance of 0.05 a) compute p ___ B) compute the corresponding standardized sample test statistics (round your answer to two decimal places) ___ C) find the p value of the test statistics (round your answer to four decimal places)___ 3) the probability of getting a number with 1 as the leading digit is about 0.301. Let us say you took a random sample of n= 220 numerical from the file and r = 50 had a first non zero digit of 1. Let p represent the population of all number that have first non zero digit of 1. A) test the claim that p is less than 0.301 use a =0.10 what is the level of significance__ B) what is the value of sample test statistics (round your answer to two decimal places)___ C)find the p value of the test statistics ( round your answer to four decimal places ___ 4) 70 % of all arrear are males 15-34 years . Supposed a police files shows that 37 arrest last month, 27 were of males age 15-34 years. Use a 5% population proportion of such arrest from 70%. A) what is the level of significance ___ B) what is the value of the sample test statistics? ( round your answer to two decimal places)____ C)find the p value of the test statistics ( round your answer to four decimal places)____ 5) women athletes have a long term graduation rate of 67%. A random sample of 36 women athletes showed that 23 eventually graduated. Does this indicate women athletes who graduate is now less than 67%? Use a 1% level of significance A) what is the level of significance ___ B) what is the value of the sample test statistics ( round your answer to two decimal places) ___ C) find the p value of the test statistics (round your answer to four decimal place)___ 6) a random sample of 50 records of automobile showed that 33 involved an intoxicated driver. Population proportion of driver fatalities related to alcohol is less than 77% in Carson County? Use a = 0.05 A) what is the level of significance ___ B) what is the value of the sample test statistics (round your answer to two decimal places) C) find the p value of the test statistics (round your answer to four decimal places)__
