Henry paid a total of $360 for the dishwasher: $20 + (10 x $34) = $20 + $340= $360
Therefore he paid $40 extra which we place over the original amount of the dishwasher:
Dividing 1 by 8 we get .125 which, when changed to a percentage becomes 12.5%
Henry paid a yearly interest rate of 12.5%

Answer:
The null and alternative hypotheses are shown below:
Part (a) 
Part (b) 
Part (c) 
Step-by-step explanation:
Consider the provided information.
We need to write the null and alternative hypotheses.
Part (a) In the 1950s, only about 40% of high school graduates went on to college.
The null hypotheses is 0.40 and alternative hypotheses is about 0.40 but not equal to 0.40.
Part (b) Twenty percent of cars of a certain model have needed costly transmission work after being driven between 50,000 and 100,000 miles. The manufacturer hopes that a redesign of a transmission component has solved this problem.
20% Cars need costly transmission and manufacture hopes that redesign of a transmission component solved this problem.
Thus, the null hypotheses is 0.20 and alternative hypotheses less than 0.20 because after redesign less than 0.20 cars needs transmission.
Part (c): We field-test a new-flavor soft drink, planning to market it only if we are sure that over 60% of the people like the flavor.
We planning to market it only if 0.60 of the people like the flavor.
Thus, the null hypotheses is 0.60 and alternative hypotheses greater than 0.60.
