Write a program to take input for n number of doctor records and write records of all cardiologists in a file named: "record1". Also write records of all those doctors in another file named: "record2" who are taking salary more than INR 80,000. After writing records in both files, merge their contents in another file: "finalrecord" and read all records of "finalrecord" file and display on screen. [Attributes of doctor: doc_id, doc_name, doc_specialization, doc_salary]

Let's see how well you understood our discussion. At this point, I want you to
solve the following problems. Show your complete solution by following the step-by-
step procedure.
1. The average number of milligrams (mg) of cholesterol in a cup of a certain brand
of ice cream is 660 mg, the standard deviation is 35 mg. Assume the variable is
normally distributed.
a. If a cup of ice cream is selected, what is the probability that the cholesterol
content will be more than 670 mg?
b. If a sample of 10 cups of ice cream is selected, what is the probability that
the mean of the sample will be larger than 670 mg?
2. In a study of the life expectancy of 400 people in a certain geographic region, the
mean age at death was 70 years, and the standard deviation was 5.1 years. If a
sample of 50 people from this region is selected, what is the probability that the
mean life expectancy will be less than 68 years?
What is the percent composition of oxygen in H2SO3?
In a redox titration, potassium permanganate, KMnO4, was standardized using a 19.60 g/L FeSO4(NH4)SO4.6H2O, (molar mass = 392.21 g/mol) standard solution. A 20.00 mL of the FeSO4(NH4)SO4.6H2O standard solution, acidified with H2SO4 was put in a conical flask. Potassium permanganate, KMnO4 was placed in the burette and the titration conducted against 20.00 mL of the FeSO4(NH4)SO4.6H2O standard solution in the conical flask.A titre volume 15.50 mL of KMnO4 solution was required to reach the end-point. The titration reaction is:
(i) Balance the above redox reaction in basic medium.
(ii) Calculate the molarity of the 19.60 g/L FeSO4(NH4)SO4.6H2O, standard solution.
(iii) Determine molarity of MnO4-(aq) in the burette.
