Hi, How do I calcuate these missing values?
The manufacturer of an MP3 player wanted to know whether a 10% reduction in price is enough to increase the sales of its product. To investigate, the owner randomly selected 8 outlets, and sold the MP3 player at its reduced price. Reported below is the number of units sold last month at the regular and reduced prices at the randomly selected outlets. Regular - 138, 127, 129, 114, 114, 126, 98 Reduced - 122, 135, 151, 133, 113, 129, 134, 133 At the 0.050 significance level, can the car manufacturer conclude that the price reduction resulted in an increase in sales? Hint: for the calculations, assume reduced price as the first sample. Compute the pooled estimate of the variance (round to 3 decimal places) Compute the test statistic (round to 2 decimal places) State your decision about the null hypothesis (Reject or Fail to reject)
