The samples are selected from the same population for each of the following, calculate now is die ference is expected on asege beweer she! sample meant one sample has m=4, the second bass n=6. and the pooled variance is 60 one sample base m=12. the second has m=15, and the pooled variance is 60 c. in part the sample sites are farger , but the pooled variance is unchanged . how does larger simple sind affect the magnitude of the standard care for the surple mean difference ?
