Answer 1

23 a) the effect of larger sample size for sampling distribution is samle mean increases and standard deviation is remains unchanged.

24) d) decreases , close to. becayse as sample size increase sample mean will go close to population mean.

25) d ) reject H0 and accept H1 because the value of z test statistic is less then the critical value of z at 5% level of significance
