create a regression model for the Wedding Cost data set, using Wedding Cost as the dependent variable, and all other variables as independent variables. Try whether the Bride and Groom were payors for the wedding, and at least one additional interaction term in the model. Do that by Excel

Using the Excel file Weddings, apply the Regression tool using the wedding cost as the dependent variable and attendance as the independent variable.

  1. What is the regression model?

  2. Interpret all key regression results, hypothesis tests, and confidence intervals in the output.

  3. If a couple is planning a wedding for 175 guests, how much should they budget?

Suppose you analyzed the ages listed on marriage licenses in Cumberland County, Pennsylvania for some period. You examine 100 licenses for your study. You find that the bride was younger than the groom for 67 couples, and the groom was younger than the bride for 27 couples. Both people listed the same age on the marriage license for the remaining 6 couples, so disregard them and consider 94 as the sample size.

Activity 6 Answers:

a) Determine a 99% confidence interval for the proportion of all marriages in this county for which the bride is younger than the groom.

b) Determine a 99% confidence interval for the proportion of all marriages in this county for which the groom is younger than the bride.

c) Comment on how the interval in part b compares to the interval in part a.

d) Comment on whether the sample data suggest that the bride is younger than the groom for more than half of the marriages in this county.

Evaluate your model using all factors outlined in the text. Assumptions, conditions, fit, outliers, etc.

Then explain your answer in words. Create a linear regression model that has 2 or 3 independent variables. Your choice of models…your choice of variables.

A1 Tim is a wedding planner. Looking at the data he has accessed, he is trying to simplify a model for how much a wedding will cost. Use the data to create a model with 2 or 3 Independent Variables, to predict Wedding Cost (dependent variable.) Evaluate your model using all factors outlined in the text.

Suppose that you are examining the difference in ages between brides and grooms. You are interested in conducting a significance test to examine to address the theory that the bride is younger than the groom in more than half of all marriages. A sample of 100 couples were observed, for which 67 had a bride younger than the groom.
