Question

As part of a study of the swimming speed of sharks, a random sample of 18 lemon sharks (Triakis semifasciata) were observed in a laboratory sea tunnel. Body lengths and maximum sustainable swimming speeds ("MSSS, " reported in body lengths per second) were measured for each shark. The computer output m a regression with y = MSSS and x = body length is given below. The null hypothesis is that there is no linear relationship between body length and maximum sustainable swimming rate. At the 0.05 level of significance, should the null hypothesis be rejected? Assume all the proper conditions are met for applying a linear regression analysis. a. Yes b. No c. There is not enough information to tell.

Explanation / Answer

Yes the null hypothesis should be rejected at 0.05 level of significnce since P-value < 0.05.
