In the US the аverаge height fоr men is 69.1 inches, оr аbоut 5 feet 9 inches. To determine if the average height for males enrolled in PSYC-330 differs from the average height of males in the US, data from the survey given during the first week of class was used to run a one-sample t-test. Below are the results comparing the average height reported by males in PSYC-330 to the average height of males in the US. Use the SPSS output tables below, to select the statements that accurately describe the results of this study. Select all statements that are true. One-Sample Statistics N Mean Std. Deviation Std.
