Question

A social psychologist reports that "ethnocentrism was significantly higher (P < 0.05) among church attenders than among non-attenders." Explain what this means in language understandable to someone who knows no statistics. Do not use the word "significance" in your answer.

Answer 1

The report claims that ethnocentrism is significantly higher among a certain group of people, which means ethnocentrism tends to be more frequently or more intensely associated with that particular group of people as opposed to another group.

Answer 2

Thank you! I already figured this one out and submitted, but thank you for getting back to me :) Can you help with this next one? @SithsAndGiggles

A 95% confidence interval for a population mean is (28, 35).

a) Can you reject the null hypothesis that µ= 34 at the 5% significance level? Why?

b) Can you reject the null hypothesis that µ= 36 at the 5% significance level? Why?

Answer 3

@SithsAndGiggles
I think I figured it out... can you check it?

34 is in your interval so it is a plausible value at the 5% level and you do not have evidence to reject the null hypothesis.
36 is outside the interval so there is evidence at the 5% sig level against the hypothesis that mu is 34.

Answer 4

Yeah that sounds reasonable to me.

Answer 5

thanks ha :)
