Two types of plastic are suitable for use by an electronics component manufacturer. The breaking strength of this plastic is important. plastic 1 is less than that of plastic 2 by 3 psi. Use α=0.05.(a) Construct the null and alternative hypothesis.(b) Calculate the P-value for this test and make your conclusion. (c) Construct an appropriate 95% confidence interval to test the hypothesis and make your conclusion using the constructed interval.

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?
