d) Based ôn you the null hypothesis? Are the data statistically significant at level a? The Toylot company makes an electric train with a motor that it claims will draw an average of only 0.8 ampere (A) under a normal load. A sample of nine motors was tested, and it was found that the mean current was x = 1.26 A, with a sample standard deviation of s=0.42 A. Do the data indicate that the Toylot claim of 0.8 A is too low? (Use a 1% level of significance.) What are we testing in this problem? ngle proportion ii) single mean (a)What is the level of significance? State the null and alternate hypotheses. (b)What sampling distribution will you use? What assumptions are you making? What is the value of the sample test statistic?
