- Biologists have theorized that male Monarch butterflies have, onaverage, a larger thorax than do females. A sample of male and femalebutterflies yielded the data at right. Use df = 22 d. At α = .05 significance, use a t test (and find the P-value) to determine whether we should reject the hypothesis that H0 : μmale = μfemale and accept the directional alternative HA: μmale > μfemale. e. At α = .05 significance, use a t test (and find the P-value) to determine whether we should reject the hypothesis that H0 : μmale = μfemale and accept the directional alternative HA: μmale < μfemale.Assume df = 13 and alpha = 0.05. If Pearson's r = 0.510, then the null _____ and the relationship between the variables is _____ . a. should be rejected; significant b. should be rejected; not significant c. should not be rejected; significant d. should not be rejected; not significantI need on answer on why you would expect these pairs of observations to be dependent?
- Compute the absolute and relative errors in using c to approximate x. x = π; c = 3.14Conduct the hypothesis test for H0: µ = 10 versus Ha: µ =/10 (i.e µ is not equal to 10) where x bar = 9.6 and s = 3, n = 50. Use alpha = .01. Explain whether we should reject or accept the null hypothesis.for qs 27 option b, how do we get the value of SSE in this case ?
