A well-known multinational FMCG produces more than fifty products and sells them in the market. Out of fifty products one is mineral water for drinking purpose and supplies different size pack bottles in the market. Product manager observed that, during hot days the sale of water is more as compared to the normal days. He started the collection of data of weekly sale of water and the average weekly temperature. Product manager was interested in developing a relationship between sales and temperature; therefore, he discussed and shared the following data with you. 75 77 69 63 79 80 77 70 73 87 72 73 80 80 69 84 77 72 74 81 sales temperature 32 36 31 31 34 29 32 35 28 31 30 31 29 35 36 28 32 33| 32 Sale is in thousand liters and temperature is in degree Celsius. Data is Normally distributed 33 You are required to determine the following information for some concrete decision: a Determine the statistical relationship between temperature and sale of water and interpret. b. How much change in sales if the temperature increases by two degrees? c. If for instance, the temperature becomes zero then how much sales will be? d. How much percent variation in sales due to temperature and due to other factors? e. Write the equation for the prediction of sales.

Question
Transcribed Image Text:A well-known multinational FMCG produces more than fifty products and sells them in the
market. Out of fifty products one is mineral water for drinking purpose and supplies different
size pack bottles in the market. Product manager observed that, during hot days the sale of water
is more as compared to the normal days. He started the collection of data of weekly sale of water
and the average weekly temperature.
Product manager was interested in developing a relationship between sales and temperature;
therefore, he discussed and shared the following data with you.
75 77 69 63 79 80 77 70 73 87 72 73 80 80 69 84 77 72 74 81

temperature 32 36 31 31 34 29 32 35 28 31 30 31 29 35 36 28 32 33| 32
Sale is in thousand liters and temperature is in degree Celsius. Data is Normally distributed
33
You are required to determine the following information for some concrete decision:
a Determine the statistical relationship between temperature and sale of water and
interpret.
b. How much change in sales if the temperature increases by two degrees?
c. If for instance, the temperature becomes zero then how much sales will be?
d. How much percent variation in sales due to temperature and due to other factors?
e. Write the equation for the prediction of sales.
