BUSINESS ANALYSIS2Part 1Answer 1The total average amount spent by the 300 customers = 25873Thus the mean average amount spent by the customers = 25873300=86.24The number of customers using BLITZ online = 66Thus the proportion of customers using BLITZ online = 66300=0.22Answer 2In order to check the validity of the claim a hypothesis was developed. Null Hypothesis: The mean average spent by the customers is more than or equal to 100H0:μ≥100Alternate Hypothesis: The mean average spent by the customers is less than 100H1:μ<100The test is a lower tail test. Since df = 299 at 0.05 level of significance CV for t = -1.650Hence, if t-statistics < -1.650 we will reject Null Hypothesisn = 300Sample Mean ́x=86.24Sample SD s = 31.90Hence Standard Error s ́x=s√n=31.90√300=1.84t-statistics t= ́x−μs ́x=100−86.241.84=−7.470The tests statistics of -7.470 is less than the CV of t of -1.650.
