- An explosion at a construction site could haveoccurred as the result of static electricity, malfunctioningof equipment, carelessness, or sabotage. Interviews withconstruction engineers analyzing the risks involved ledto the estimates that such an explosion would occur withprobability 0.25 as a result of static electricity, 0.20 as aresult of malfunctioning of equipment, 0.40 as a result ofcarelessness, and 0.75 as a result of sabotage. It is alsofelt that the prior probabilities of the four causes of theexplosion are 0.20, 0.40, 0.25, and 0.15. Based on all thisinformation, what is(a) the most likely cause of the explosion;(b) the least likely cause of the explosion?The television show Lett3rs has been successful for many years. That show recently had a share of 19, which means, that among the TV sets in use, 19% were tuned to Lett3rs. An advertiser wants to verify that 19% share value by conducting its own survey, and a pilot survey begins with 10 households have TV sets in use at the time of a Lett3rs broadcast. If at most one household is tuned to Lett3rs, does it appear that the 19% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Lett3rs unusual?) A. no, it is not wrongB. yes, it is wrongThe television show CSI: Shoboygan has been successful for many years.

- The past records of a supermarket show that its customers spend an averageof $95 per visit at this store. Recently the management of the store initiated a promotionalcampaign according to which each customer receives points based on the total moneyspent at the store, and these points can be used to buy products at the store. Themanagement expects that as a result of this campaign, the customers should beencouraged to spend more money at the store. To check whether this is true, the managerof the store took a sample of 14 customers who visited the store. The following data givethe money (in dollars) spent by these customers at this supermarket during their visits. 109 136 107 116 101 109 110 94 101 97 104 83 67 120Assume that the money spent by all customers at this supermarket has a normaldistribution. Using a 5% significance level, can you conclude that the mean amount ofmoney spent by all customers at this supermarket after the campaign was started is morethan $95?For example, for student ID s1243657, the 4th digital of s1243657 is “3”, therefore variable “A” is “Use interactive activities”; the 5th digital of s1243657 is “6”, therefore variable “B” is “Give a lot of assignments”; the 6th digital of s1243657 is “5”, therefore variable “C” is “Good communication skills.
