b-1. Calculate the value of the test statistic with z=438 and n=90. (Negative value should be indicated by a minus sign. Round final answer to 2 decimal places.) Test statistic -573 b-2. What is the conclusion at the 5% significance level? O Reject He since the p-value is greater than the significance level. O Reject since the p-value is less than the significance level. O Do not reject O Do not reject since the p-value is greater than the significance level. since the p-value is less than the significance level.
b-2. What is the conclusion at the 5% significance level? O Reject He since the p-value is greater than the significance level. O Reject He since the p-value is less than the significance level. O Do not reject H₂ since the p-value is greater than the significance level. O Do not reject He since the p-value is less than the significance level. b-3. Interpret the results at a = 0.05. O We conclude that the population mean differs from 470. We cannot conclude that the population mean differs from 470. We conclude that the sample mean differs from 470. We cannot conclude that the sample mean differs from 470.
