I guess the correct answer is Scientific Law.
Scientific Law is rule of nature that tells you what will happen under certain conditions.
Delivering all the check all
together is a classic example of Bundling. It is a marketing strategy that
joins products or services together in order to sell them as a single combined
unit this allows the convenient purchase of several products and/or services
from one company. The services and products are practically related, but they
can also be of dissimilar products which appeal to one group of customers.

The formula for calculating the Confidence Interval is as
follows:
Confidence Interval = x +- (z*s)/√N
Where:
x = mean = 10.36
z = taken from standard normal distribution table based on 95%
confidence level = 1.96
s = standard deviation = 5.31
N = sample size = 30
Substituting know values on the equation:
Confidence Interval = 10.36 +- ( 1.96 * 5.31) / √30
Confidence Interval = 8.46 and 12.26
Hence the bill of lunch orders ranges from 8.46 to 12.26.

Answer:
It is both qualitative data and primary data.
Explanation:
Qualitative data is data that is not expressed in numerical values. Kay & Maggie are asking for opinons in the survey and interviews. These opinons are not numbers, they are words, language, therefore, they are qualitative.
It is primary data because Kay & Maggie are collecting the information directly from the desired source, the customers, instead of collecting the data from a third party.
Answer: a. 2.90%
b. 2.81%
Explanation:
Nominal rate = 6%
Inflation rate = 3.1%
a. What is the approximate real rate of interest?
The approximate real rate of interest will be calculated as:
= Nominal rate - Inflation rate
= 6.0% - 3.1%
= 2.90%
b. What is the exact real rate?
Exact real rate will be calculated as:
= (nominal-inflation) / (1+inflation)
= (6.0% - 3.1%) / (1 + 3.1%)
= 2.9% / 1.031
= 2.81%
