#1 part A.) To test H0: μ=100 versus H1: μ≠100, a random sample of size n=20 is obtained from a population that is known to be normally distributed. Complete parts (a) through (d) below. (aa.) If x̅=104.4 and s=9.4, compute the test statistic. t0 = __________ (bb.) If the researcher decides to test this hypothesis at the α=0.01 level of significance, determine the critical value(s). Although technology or a t-distribution table can be used to find the critical value, in...
To test Ho: = 50 versus H=50, a simple random sample of size n = 40 is obtained. Complete parts (a) through below Click the icon to view the table of critical t-values (a) Does the population have to be normally distributed to test this hypothesis by using t-distribution methods? Why? O A. No-there are no constraints in order to perform a hypothesis test. O B. No-since the sample size is at least 30, the underlying population does not need...
