Directions Determine whether each of the following variables would best be modeled as continuous or discrete.
(Example 1)
a. The height of a high-rise apartment building
b. The number of floors in a high-rise apartment building

Check whether the following variables are discrete or continuous variables.
a. The height of a high-rise apartment building
b. The number of floors in high-rise apartment building
Answer to Problem 1SE
a. The height of a high-rise apartment building is a continuous variable.
b. The number of floors in high-rise apartment building is a discrete variable.
Explanation of Solution
a.
The height of a high-rise apartment building is a continuous variable because it can take any value between a specified range, that is, the height can be 20.5 meters, 16.7 meters and so on.
b.
The number of floors in a high-rise apartment building is a discrete variable because it can only take finite and discrete values. The number of floors a building can have is

The company defines a "high-sales day" that is, any day with sales exceeding $4800. please provide a step by step on how to get the answers in excel Q: What percentage of days can the company expect to have "high-sales days" or sales greater than $4800? Q: What is the sales revenue threshold for the bottom 10% of days?

You aim to test whether the actual average daily sales differ significantly from this claimed value. You can provide your answer by inserting a text box and the answer must include: Null hypothesis, Alternative hypothesis, Show answer (output table/summary table), and Conclusion based on the P value.
