The Watch Corporation of Switzerland claims that its watches on average will neither gain nor lose time during a week. A sample of 18watches provided the following gains (+) or losses (-) in seconds per week+0.42-e.350.12e.590.210. 59-0.71e.740.62-0.890.69-0.670.30-0.40-0.36 0.540.410.74Ho H=0Is it reasonable to conclude that the mean gain or loss in time for the watches is 0? Use the 010 significance level.a. At a level of 0.10 significance, we reject Ho: µ = 0. (Negative answer should be indicated by a minus sign. Round the final answersto 3 decimal places.)If r<or t>reject Hob. What is the value of the test statistic? (Round the final answer to 3 decimal places.)Value of the test statistic =

Data analysis, please show all work A company makes a laser product. The product is well made, but is expensive to manufacture. As indicated, the product is well made, so 98.7% of lasers function as advertised. However, 1.3% are returned for being defective. For each laser they manufacture, the company makes $204 in profit. However, when the product is defective, it costs the company $1340 (in shipping refunds, repair, etc). How much can the company expect to make (or lose!) each time they sell a laser?
