PART A
Assuming that the population variances for developed countries and emerging countries are equal, is there evidence of a difference in the mean time required to start a business between developed countries and emerging countries? (Use a = 0.05) Let m1 be the mean time required to start a business in developed countries and let m2 be the mean time required to start a business in emerging countries.
the null hypothesis is Ho: m1 = m2
the alternative hypothesis is H1: m1 is not equal to m2
what is the test statistic?
what are the critical values?
state the conclusion?
a- reject ho there is sufficient evidence
b- reject ho there is insufficient evidence
c- do not reject ho there is sufficient evidence
d- do not reject ho there is insufficient evidence
part b
determine the p value?
interpret the meaning
a- the p value is the probability of 2 samples, one taken from each of the two populations , have a mean differnece greater than or equal to the mean difference of these two samples there is no difference in the true population means
b- the p value is the probability that the null hypotheisis is true
c-the p value is the probability of 2 samples, one taken from each of the two populations, have a mean difference less than or equal to the mean difference of these two samples there is a difference in the true population means
d-the p value is the probability of 2 samples, one taken from each of the two populations, have a mean difference equal to the mean difference of these two samples
part c
in addition to equal variance what other assumption is necessary in a ?
a- the two populations have equal standard deviations
b-the two sample sizes are equal
c- the hypothesis test must be a two tail test so the results can be validly compared to a 95% confidence interval
d- the two populations are normally distributed
part d
construct a 95% interval estimate of the difference betweeen the populations mean of developed countries and emerging countries
blank is less thsn or equal to m1- m2 which is less than or equal to blank
