Given the following hypotheses: h0: μ = 520 h1: μ ≠ 520
a random sample of 18 observations is selected from a normal population. the sample mean was 529 and the sample standard deviation was 5. using the 0.01 significance level:
a) state the decision rule. (negative amount should be indicated by a minus sign. round your answers to 3 decimal places.) reject h0 when the test statistic is inside or outside? the
b)compute the value of the test statistic. (round your answer to 3 decimal places.)
c)what is your decision regarding the null hypothesis? reject or do not reject?
