- What is meant by the sample space of an experiment?A manufacturer of nickel-hydrogen batteries randomly selects 100 nickel plates for test cells, cycles them a specified number of times, and determines that 14 of the plates have blistered. Does this provide compelling evidence for concluding that more than 10% ofplates blister under such circumstances?A) State H0 and Ha B) Test the hypothesis using the P-Value approach at a significance level of 4.5%, and express your decision. C) Based on the given data, determine the extreme value without rejecting the H0.A well-known brokerage firm executive claimed that at least 90% of investors are currently confident of meeting their investment goals. An XYZ Investor Optimism Survey, conducted over a two week period, found that in a sample of 800 people, 88% of them said they are confident of meeting their goals. What practical conclusion can we make about the claim? What would be our formal conclusion if we used a 0.01 significance level?
