Running is among the most popular sports worldwide, allowing the market for sports accessories for both professional and non-professional athletes to expand and grow in the past few years. A sportswear company has come up with a new sports watch and, to promote the product, is planning to offer a free half marathon training plan with it. To evaluate the effectiveness of the training plan, they study a group of 40 non-professional runners who participated in a half marathon before and after using the training plan. Their findings are stored in the file RunTime . Compute descriptive statistics and perform a paired \(t\) test. State your findings and conclusions in a report. (Use the 0.05 level of significance.)
