(Round all intermediate calculations to at least 4 decimal places.) In order to conduct a hypothesis test for the population variance, you compute s2 = 68 from a sample of 12 observations drawn from a normally distributed population. Use the critical value approach to conduct the following tests at α = 0.05. Use Table 3. H0: σ2 ≤ 37; HA: σ2 > 37 a-1. Calculate the value of the test statistic. (Round your answer to 2 decimal places.)...

#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...

The FAA standard average weight for a passenger's carry-on items (personal items plus carry-on bags) is 16 pounds Many airline companies have begun implementing fees for checked bags. Economic theory predicts that passengers will respond to the increase in the...
