- Changing alpha from .05 to .10 increases the risk of a Type I error. true or flase?A researcher collects data that represents the average number of hours of sleep in the last two nights by 8 depressed patients and 9 non-depressed patients. The researcher is interested in whether the two groups reliably differ in the amount of sleep they get. Use Jamovi to calculate t-obt and the p value.what would the p-value for this be? thank you !
