I need an explanation for this Statistics question to help me study.
1c) we are using 5 as our cut off. not 10
1e) this will not suffice as interpretation. please look at the worksheet or review to interpret the p-value correctly
9d) did you use the t-table to get the p-value? if so you should get a range of values specifically .002 to .005
9e) again this is incorrect interpretation
9h) you need to use x-bar for the confidence interval formula. so use 8.25 instead of 8. Then once you make the interval you see if 8 is in the interval to make your conclusion.
7) is wrong as well. you simply need to see if .8 falls in the interval. since it does that means it is a plausible value for the true proportion. Therefor we can not reject it.
