What are the 30 variables I need to put in the SPSS stats data editor to get this output? One-Sample t-test: Data set: A real dataset from Kaggle on the heights of students in a university. The research question is whether the average height of students in the university is significantly different from 170 cm. The hypothetical study includes a random sample of 30 students from the university, and their heights are measured in cm. Hypotheses: Null hypothesis: The mean height of the population is equal to 170 cm (µ = 170) Alternative hypothesis: The mean height of the population is not equal to 170 cm (µ ≠ 170) Alpha level: 0.05 SPSS Output: N Mean Std. Deviation Std. Error Mean 30 172.2 6.43 1.18 One-Sample Test Test Value = 170 95% Confidence Interval of the Difference t df Sig. (2-tailed) Mean Difference Lower Upper 2.10 29 0.046 2.20 0.09 4.31 The output includes the sample size (N), mean, standard deviation, and standard error mean for the height variable. It also shows the results of the one-sample t-test, including the test value, t-value, degrees of freedom (df), p-value (Sig.), and the mean difference with its 95% confidence interval (Lower and Upper). Since the p-value is less than the alpha level of 0.05, we can reject the null hypothesis and conclude that there is sufficient evidence to suggest that the average height of students in the university is significantly different from 170 cm.
