In proton beam therapy, a beam of high-energy protons is used to kill cancerous cells in a tumor. In one system, the beam, which consists of protons with an energy of 2.8×10−11J, has a current of 72 nA. The protons in the beam mostly come to rest within the tumor. The radiologist has ordered a total dose corresponding to 3.8×10−3J of energy to be deposited in the tumor.
Part A How many protons strike the tumor each second? Express your answer as a number of protons.
Part B: How long should the beam be on in order to deliver the required dose?

(a) Find the margin of error for the given values of c, σ, and n. c = 0.90, σ = 3.8, n = 100
E= _ (Round to three decimal places as needed.)
(b) Construct the confidence interval for the population mean μ.
c = 0.90 , x=9.1, σ = 0.3 , and n = 47
A 90% confidence interval for μ is _, _ (Round to two decimal places as needed.)
(c) Construct the confidence interval for the population mean μ.
c=0.95 , x=16.2, σ =2.0, and n =35
A 95% confidence interval for μ is _, _ (Round to two decimal places as needed.)

You entered into a currency swap that has 4.25 years left until termination. You receive 4.3% on $10,000,000 (annual rate with annual compounding) and pay 3.8% on on €9,500,000 each settlement date. Current exchange rate is $1.10/€1. The interest rates are listed below for the USD and EUR all quoted per annum with continuous compounding. What is the value of your swap today? LOOKING FOR EXPLANATION AND IN SOME SORT OF EXCEL FORMAT PLEASE :)
