Good Day! May I ask for a hand with the following activities, thank you so much, and God Bless!
Read and analyze the following questions listed below. Then provide answers (discussions)/solutions as directed for each of the following items.
1. A marketing manager plans to market and sell a certain product to improve
companies profit. Which of the following can be a better choice for the manager?
Justify your answer.
Product A: Product A with Mean profit of Php 100,000; standard deviation of Php 2,000
Product B: Product B with Mean Profit of Php 100,000; standard deviation of Php 2,500.
2. Reflect
a. If all the data in a given sample are the same, what is the standard deviation of the sample? Justify your answer.
b. If the given two sample data sets have the same standard deviation, are these samples necessarily identical? Justify your answer.
3. Search for a real-life problem or phenomenon that has an existing data values. Then construct the Box-and-Whisker plot that shows the underlying distribution for the data.
4. Briefly discuss the other uses of Box-and-Whisker plot in data exploration?
5. Look or search for a real-life problem or phenomenon in your respective field of discipline and consider two important and related variables that have existing data set. Then perform/ find the following:
a. Determine the linear correlation coefficient for the relationship between the two chosen variables.
b. Interpret the strength of the relationship for the two variables based on the calculated Pearson r value in (a).
c. Find the prediction equation of the regression line for the data using the least
squares method.
d. Construct the scatter plot of the data and the regression line.
I hope I can ask for your help. Thank you!
