What is the z statistic and critical z value(s)? 5ParagraphA research institute examined the IQs (intelligence quotients) in American adults and reported a mean(u) of 100 points and a standard deviation (o) of 15 points. But I wonder if the statistics in my city,Chicago, would be different from the national average. Specifically, I have a hunch that individuals inChicago might have higher IQs compared to the national average.StylesTo test this idea, I randomly picked 18 friends of mine living in Chicago and asked them their individualIQs. The data set is shown below. (The same data are also provided in an Excel file if you choose to useExcel for your calculations.)I would like to perform a Z test to see if the IQs in Chicago (represented by the sample of 18 individuals)are significantly higher than the national average IQ. The significance level for my Z test was set at a =05. The hypotheses should be directional because I am predicting a specific direction of difference, andthe test should be one-tailed.Editing igateSubject123456789PSY230 MillerDill copere contient and matural scieną duszpanelPER MANGE t the usbrucken vill se destaEURE COUPEZSeasonal must strani ter uploading to any course shell,comply with applicable prefekk bra Coulty member10111213BHSK7%14151617IQ901810896989412892100114122134941121098711592118

Using Excel Tablet’s hardness can be represented by its relative density and tensile strength. Studies have indicated that its tensile strength depends on the relative density, regardless of production shifts. Recently, a batch was found to produce cluster of tablets that show low relative density values of 68%, 74.3%, and 80.1%. Based on the current data in April 2022, what is the prediction of the tensile strength for such tablets? Present the requires analysis and comment on the validity of the model that you have used to carry out this prediction.
