1-State whetherbeach othe following true or false, and explain why

A) a high negative correlation value, for example, p=-.95, means that the value of the regression line slope, beta, must be a large negative number

B)if a t-test of the hypothesis H0: p=0 versus Ha: p not equal to 0 is rejected at the alpha=0.05 level, then p cannot be a number very near zero.

2-suppose the correlation coefficient between FEV for 100 sets of identical twins is 0.7, whereas the true correlation between fraternal twin is known to be 0.38. Carry out the appropriate hypothesis test for testing the null hypothesis that the correlation between FEV values is greater among identical twins than among faternal twins.
