Question

**Times for a Table**

Dominick Aldo owns and operates
Carolina’s which is an Italian restaurant in New York. The Excel
file **Single Population.xlsx** is shown below and
contains the amount of time that table times varied from table to
table. Test the hypothesis that the average table time exceeds 98
minutes using α = 0.05. What is the *p*-value? Interpret the
results.

(Step 1) Identify the Null Hypothesis ad Alternative Hypothesis

(Step 2) Calculate the test statistic

(Step 3) Calculate the p-value and critical value

(Step 4) What is your conclusion about the Null Hypothesis?

(Step 5) What is your final conclusion about the Original Claim?

Answer #1

**Solution:**

Identify the Null Hypothesis ad Alternative Hypothesis

Calculate the test statistic.

The test statistic is:

Where:

The critical value is:

What is your conclusion about the Null Hypothesis?

**Answer: Since the test statistic does not fall in the
rejection region, we, therefore, fail to reject the null
hypothesis.**

What is your final conclusion about the Original Claim?

**Answer: Since we fail to reject the null hypothesis,
therefore, there is not sufficient evidence to support the claim
that the average table time exceeds 98 minutes**

Suppose that you are responsible for making arrangements for a
business convention and that you have been charged with choosing a
city for the convention that has the least expensive rooms. You
have narrowed your choices to Atlanta and Houston. The table below
contains samples of prices for rooms in Atlanta and Houston.
Because considerable historical data on the prices of rooms in both
cities are available, the population standard deviations for the
prices can be assumed to be $35...

The data below represents height in inches/weight in pounds.
Clearly identify the dependent and independent variables as well as
the domain and range. Choose any two points from the data using
different independent variables and use those two points to
determine the rate of change (slope). Then, using the dependent
data value of -500 as your initial value, write an equation for the
linear function model. Predict what you expect at a height of
75".
