The manufacturer of hardness testing equipment uses steel-ball indenters to penetrate metal that is being tested. However, the manufacturer thinks it would be better to use a diamond indenter so that all types of metal can be tested. Because of differences between the two types of indenters, it is suspected that the two methods will produce different hardness readings. The metal specimens to be tested are large enough so that two indentions can be made. Therefore, the manufacturer uses both indenters on each specimen and compares the hardness readings. Construct a 95% confidence interval to judge whether the two indenters result in different measurements. Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers.

TMA manufactures 37-in. high definition LCD televisions in two separate locations, Locations I and II. The output at Location I is at most 6000 televisions/month, whereas the output at Location II is at most 5000 televisions/month. TMA is the main supplier of televisions to the Pulsar Corporation, its holding company, which has priority in having all its requirements met. In a certain month, Pulsar placed orders for 3000 and 4000 televisions to be shipped to two of its factories located in City A and City B, respectively. The shipping costs (in dollars) per television from the two TMA plants to the two Pulsar factories are as follows.
| From TMA | City A | City B |
| Location I | $5 | $3 |
| Location II | $7 | $8 |
TMA will ship x televisions from Location I to city A and y televisions from Location I to city B. Find a shipping schedule that meets the requirements of both companies while keeping costs to a minimum.

Write this program in a C++ language Calculate the ideal age of a spouse. Enter either m or f from the keyboard in lower case. You may use string data for the gender. Convert the gender to upper case
Enter an age from the keyboard, probably an integer
You will need prompts telling the user what to enter.
Use an IF statement to determine if the person is a male or female. You do one calculation if the person is a male else you do another calculation if the person is a female.
Use a loop where you enter this data (loop for 1 to 6 ) so you will only have to run the program 1 time instead of 6 times.
m 28
m 70
m 18
f 32
f 60
f 13
For each set of data, print out the Gender, age, and Ideal Spouse's age, along with the following messages when they apply (the messages will be in the last column):
If a male over 60, print “robbing the cradle.”
If a male under 25, print “too young to be married”
if a female over 60, print “a gold digger”
if a female < 19 print “jail bait”
Plato's formula. A little bit out of date. You will be a gold digger or robbing the cradle if your age is over 40 because back then people only lived to be about 35 or so on the average.
For a male, his ideal spouse’s age is his age/2+7
For a female, her age*2-14
So, inside the loop
1. Input from the keyboard either m or f and an age
2. convert the m or f to upper or upper case
3. enter age from keyboard
4. Use an if to determine if user is a male or female. Use the appropriate syntax for your language. Calculate Ideal age.
5. Print the Gender as “Male” or as “Female”, and the age, and the ideal age you calculated.
6. Then print any matching messages on the same line
7. Accumulate the total idea age of a male spouse and of a female spouse and the count of males and females.
8. When you exit the loop the print the average idea age of a spouse for a male and the average ideal age of a spouse for a female.
if gender=="M"
do male calculation
else
do female calculation
remember two = signs for comparison
You will need braces for code blocks
