Select Select is less than is greater than is equal to is not equal toSelect Select is less than is greater than is equal to is not equal toThe following situation Calls for a signicance test for a population mean [1. State the null hypothesis H6 and the alternative hypothesis H5. Census Bureau data show that the mean household income in the area sewed by a shopping mall is $42,500 per year. A market research rm questions shoppers at the mail. The researchers suspect the mean household income of mail shoppers is higher than that of the general population. Ha: u w,soo Ha: u $42,500 A pharmaceutical manufacturer forms tablets by compressing a granular material that contains the active ingredient and various fillers. The hardness of a sample from each lot of tablets produced is measured in order to control the compression process. The target values for the hardness are u = 11.5 and o = 0.23. The hardness data for a sample of 16 tablets are given below. 11.587 11.37 11.398 11.65 11.328 11.3 11.349 11.377 11.573 11.587 11.678 11.573 11.349 11.538 11.538 11.552 Is there significant evidence at the 5% level that the mean hardness of the tablets is different from the target value? Use the Inference Toolbox. Z = P-value = Conclusion O There is significant evidence that the mean hardness of the tablets differs from the target value. O There is no evidence that the mean hardness of the tablets differs from the target value.A random number generator is supposed to produce random numbers that are uniformly distributed on the interval from 0 to 1. If this is true, the numbers generated come from a population with u = 0.5 and o = 0.2877. A command to generate 92 random numbers gives outcomes with mean x = 0.4383. Assume that the population o remains fixed. We want to test the following hypotheses. Ho: M = 0.5 Ha: H = 0.5 (a) Calculate the value of the z test statistic. (b) Is the result significant at the 5% level (a = .05)? O yes O no (c) Is the result significant at the 1% level (a = .01)? O yes O no (d) Between which two normal critical values in the bottom row of Table C does z lie? O z
