A researcher wants to test whether a certain sound will make rats do worse on learning tasks. It is known that an ordinary rat can learn to run a particular maze correctly in 19 trials, with a standard deviation of 5.(The number of trials to learn this maze is normally distributed.) The researcher now tries an ordinary rat in the maze, but with sound. The rat takes 35 trials to learn the maze. Complete parts a and b below. (a)...

Consider conducting a hypothesis test in which the null and alternative hypotheses are: Ho: ? ? c Ha: ? > c Where c is some hypothesized value. Suppose the significance level is 0.02, the test statistic is positive, and the statistical decision is to FTR Ho. If we redo the test at ? = 0.05, our statistical decision would be: ---Select--- There is not enough information to make a decision at 0.05 FTR Ho at ? = 0.05 Reject Ho at...

Suppose a researcher is testing the hypothesis Ho: p = 0.6 versus H1:p*0.6 and she finds the P-value to be 0.29. Explain what this means. Would she reject the null hypothesis? Why? Choose the correct explanation below. O A. If the P-value for a particular test statistic is 0.29, she expects results no more extreme than the test statistic in about 29 of 100 samples if the null hypothesis is true. OB. If the P-value for a particular test statistic...
