The main number of English courses taken in a two-year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 29 males and 16 females. This males took an average of three English courses with a standard deviation of 0.8. The females took an average of four English courses with a standard deviation of 1.0. Are the means statistically the same? Assume that the variances are not equal. Test at 5% level of significance. Subscripts: 1: males; 2: females What is the question/claim to be tested in symbols the hypothesis is Ho: Ha: which hypothesis matches the claim test objective is to reject or support level of significance a=.05 type of test (left, right, two-tailed) the applicable test to be applied is (2-sampZTEST/2-sampTTEST, 2-propZTEST) calculate the applicable test to be applied is (2-sampZTEST/2-sampTTEST, 2-propZTEST) calculate the applicable test statistic z or t= p-value= compare p-value to a (eg. p-value greater than or less than a) decision (reject Ho/Failed to reject) evidence (enough/not enough) test objective is to (reject/support): conclusion: at ____ level of significance, _____ _____ that the mean number of English courses taken in a two- year time period by male and female college students is believed to be about the same

Subscripts: 1: males; 2: females
What is the question/claim to be tested in symbols
the hypothesis is
Ho:
Ha:
which hypothesis matches the claim
test objective is to reject or support
level of significance a=.05
type of test (left, right, two-tailed)
the applicable test to be applied is (2-sampZTEST/2-sampTTEST, 2-propZTEST)
calculate the applicable test to be applied is (2-sampZTEST/2-sampTTEST, 2-propZTEST)
calculate the applicable test statistic
z or t=
p-value=
compare p-value to a (eg. p-value greater than or less than a)
decision (reject Ho/Failed to reject)
evidence (enough/not enough)
test objective is to (reject/support):
conclusion:
at ____ level of significance, _____ _____ that the
