The manufacturer of an MP3 player wanted to know whether a 10% reduction in price is enough to increase the the sales of its product. To investigate, the owner selected randomly selected eight outlets and sold the MP3 player at reduced price. At seven randomly selected outlets, the MP3 player is sold at regular price. The table below reports both sales numbers at reduced and regular sales price. Regular price 138 121 88 115 141 125 96 Reduced 128 134 price 152 135 114 106 112 120 What is the decision, conclusion and the pooled variance ? Select one: a.Do not reject H evidence of an increase in sales, 0.334 b.Do not reject H, no evidence of an increase in sales,16.46. c.Do not reject H. no evidence of an increase in sales, 16 46 d.Do not reject Hno evidence of an increase in sales, 305.708 e.Reject H, and evidence of an increase in sales, 122278
