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 ofninemotors was tested, and it was found that the mean current wasx=1.30A,with a sample standard deviation ofs=0.44A.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?single meansingle proportion (a) What is the level of significance? State the null and alternate hypotheses.

H₀:= 0.8;H₁:> 0.8H₀:p= 0.8;H₁:p> 0.8 H₀:= 0.8;H₁:0.8H₀:p0.8;H₁:p= 0.8H₀:p= 0.8;H₁:p0.8H₀:0.8;H₁:= 0.8

(b) What sampling distribution will you use? What assumptions are you making?

The Student'st, since we assume thatxhas a normal distribution with unknown.The standard normal, since we assume thatxhas a normal distribution with known. The standard normal, since we assume thatxhas a normal distribution with unknown.The Student'st, since we assume thatxhas a normal distribution with known.

What is the value of the sample test statistic? (Round your answer to three decimal places.) (c) Find (or estimate) theP-value.
