Question
I need a report on the folleoing data please (Not Calculation i done calculation already just write report please )
You are a consultant who works for the Diligent Consulting Group. Your client, the New Star Grocery Company, believes that there may be a relationship between the number of customers who visit the store during any given month (“customer traffic”) and the total sales for that same month. In other words, the greater the customer traffic, the greater the sales for that month. To test this theory, the client has collected customer traffic data over the past 12-month period, and monthly sales for that same 12-month period (Year 1).
Length requirements: 4–5 pages minimum (not including Cover and Reference pages). NOTE: You must submit 4–5 pages of written discussion and analysis. This means that you should avoid use of tables and charts as “space fillers.”
Provide a brief introduction to/background of the problem.
Your written (in Word) analysis should discuss the logic and rationale used to develop the LR equation and chart.
Provide complete, meaningful, and accurate recommendation(s) concerning how the New Star Grocery Company might use the LR equation to forecast future sales. (For example, how reliable is the LR equation in predicting future sales?) What other recommendations do you have for the client?

Here dependent variable (Y) = sales
And independent variable (X) = customers
Here we have to fit regression and find scatter plot and analyze and interpret the data.
This we can done in MINTAB.
steps :
ENTER data into MINITAB sheet --> STAT --> Regression --> Regression --> Response : select sales column --> Predictors : select customers column --> Results : select second options --> ok --> ok

Regression Analysis: Sales ($000) versus Customers
The regression equation is
Sales ($000) = 112 + 0.648 Customers
Predictor Coef SE Coef T P
Constant 111.65 39.23 2.85 0.017
Customers 0.6480 0.1284 5.05 0.001
S = 33.0385 R-Sq = 71.8% R-Sq(adj) = 69.0%
Analysis of Variance
Source DF SS MS F P
Regression 1 27791 27791 25.46 0.001
Residual Error 10 10915 1092
Total 11 38707
Here intercept (b0) = 112
slope (b1) = 0.648
Interpretation of slope :
For one unit change in customers will be 0.648 unit increase in sales.
Overall significance and individual significance:
We can test the same hypothesis using overall significance and individual significance.
Here we can test the hypothesis that,
H0 : B = 0 Vs H1 : B not= 0
where B is population slope for customers.
Assume alpha = level of significance = 0.05
Here for overall significance test statistic follows F-distribution and for individual significance test statistic follows t-distribution.
F = 25.46
P-value = 0.001
T = 5.05
P-value = 0.001
Here P-value < alpha
Reject H0 at 0.05 level of significance.
COnclusion : The population slope for customers is differ than 0.
OR customers is significant variable.
R-sq = 71.8%
Interpretation : It expresses the proportion of variation in sales which is explained by variation in customers.
