Write a program that computes the tax and tip on a restaurant
bill for a patron with $44.50 meal charge. The tax should be 6.75%
of the meal cost. The tip should be 15% of the total after adding
tax. Display the meal cost, tax amount, tip amount, and total bill
on the screen. (I need this to be in OOP using C++)

A restaurant wants to estimate the average bill paid by a party
of two for dinner (service hours after 5 p.m.) They take a random
sample of 100 bills and find that they average $80 with a standard
deviation of $40. In making an 80% confidence interval for the
parameter of interest, they should get a margin of error of
about
± $80
± $50
± $10
± $5

In this exercise, you will complete the Restaurant Tip
application from Chapter 2’s Focus on the Concepts lesson. The
application’s Planning Chart is shown in Figure 3-34.
Use either a flowchart or pseudocode to plan the btnCalc_Click
procedure, which should calculate and display a server’s tip.
Open the Tip Solution.sln file contained in the
VB2017\Chap03\Tip Solution folder. Enter the three Option
statements in the Code Editor window. Use the comments as a guide
when coding the btnCalc_Click procedure. Be sure...

Women’s hands are 6.9 inches on average (from the tip of the
middle finger to the heel of the hand). The standard deviation is
0.34 inches. Assume that hand length is normally distributed.
A.) What is the probability that a woman would have a hand
length longer than 7.58 inches? Show your work. Start by finding
the z-score for 7.58 and then use what you know about the normal
distribution to find the probability.
B.) What is the probability that...

You work at Happy Joe's family restaurant and want to see if
customer meal satisfaction and gender are related to one another.
You take a sample of customers and ask them if they were satisfied
with their meal and note their gender. To test at the 0.1 level to
determine if Satisfaction and Gender are dependent, calculate the
chi-square test statistic and p-value.

A restaurant that bills its house account monthly is concerned
that the average monthly bill exceeds $200 per account. A random
sample of 16 accounts is selected, resulting in a sample mean of
$210 and a standard deviation of 20. Using a level of significance
of 0.01, can we conclude that the average monthly bill is greater
than $200 per account?

The average starting salary of students who graduated from
colleges of Business in 2009 was $48,800. A sample of 100 graduates
of 2010 showed an average starting salary of
$50,000. Assume the standard deviation of the
population is known to be $7000. We want to
determine whether or not there has been a significant
increase in the starting salaries.
a.
State the null and alternative hypotheses to be tested.
b.
Compute the test statistic.
c.
The null hypothesis is to...
