Conduct the hypothesis test and provide the test statistic, critical value, and P-value, and state the conclusion. A person randomly selected 100 checks and recorded the cents portions of those checks. The table below lists those cents portions categorized according to the indicated values. Use a 0.10 significance level to test the claim that the four categories are equally likely. The person expected that many checks for whole dollar amounts would result in a disproportionately high frequency for the first category, but do the results support that expectation?
Cents portion of check: 0-24, 25-49, 50-74, 75-99

16. You are planning to build a solar powered spaceship with mass of 100,000 kg using a reflective solar sail with dimensions of 5km x 5km. Assuming an average solar intensity of 1200 W/m 2 , calculate the maximum radiation pressure exerted on the sails.
17. Unpolarized light of intensity I = 100 W/m2 is transmitted through 3 polarizers with axes oriented as follows: P1 = +x axis, P2 = 30 degrees relative to the +x-axis, and P3 = -45 degrees relative to +x-axis. Calculate the output intensities I1 from the first polarizer, I2 from the second polarizer, and I3 from the third polarizer.

Suppose there is only one bank in the economy, Happy Bank. The citizens in this economy have 20 million in money, and they have all deposited their money in Happy bank.
a. happy bank decides on a policy of holding 100% reserves. draw a T-account for the bank.
b. Now, happy bank is required to hold 5% of its existing 20 million as reserves, and to loan out the rest. Draw a T-account for the bank after this first round of loans has been made.
c. Assume that Happy Bank is part of a multi-bank system. How much is the amount of money created through the multiple expansion of credit? How much is the total money supply in this economy?

The first two questions pertain to the preparation of buffer using separate amounts of a weak acid and the salt of its conjugate base. Calculate the amounts of each needed to achieve the required concentrations or pH.
1) You need to prepare a 100 mL solution that is both 0.03 M sodium acetate and 0.02 M acetic acid. You have solid sodium acetate trihydrate and 1 M acetic acid solution. Show calculations and describe how to do this.
2) You need to make a solution that has pH of 4.6 from sodium acetate/acetic acid. Calculate the needed concentrations if the sum of the molarities of sodium acetate/acetic acid is 0.05 M.
