Assignment:
The Cell Tone Company sells cellular phones and airtime in several states. At a recent meeting, the marketing manager stated that the median age of its customers is less than 40. This came up in conjunction with a proposed advertising plan that is to be directed toward a young audience. Before actually completing the advertising plan, Cell Tone decided to randomly sample customers. Among the questions asked in a survey of 50 customers in the Jacksonville, Florida, area was the customers’ ages. The data are in the file Cell Phone Survey.
a. Examine the sample data. Is the variable being measured a discrete or a continuous variable? Does it seem feasible that these data could have come from a normal distribution?
b. The marketing manager must support his statement concerning customer age in an upcoming board meeting. Using a significance level of 0.10, provide this support for the marketing manager.
Provide complete and step by step solution for the question and show calculations and use formulas.
