Assuming that the populations are normally distributed and demonstrate homogeneity of variance,
the researcher uses a t test to determine if there is a significant difference between the two groups.
She believes that the scores of single people will be significantly higher than that of married people
for work-balance satisfaction, and thus conducts a one-tail hypothesis test.
The researchers would use the following hypotheses:
Null hypothesis, Ho to be $\mu(single) - \mu(married) = 0$
Alternative hypothesis, H1 to be $\mu(single) - \mu(married) > 0$
Please conduct a t test to determine whether there is a difference between these two independent
means. Please determine the following values:
pooled variance = [Select]
standard error = [Select]
The t statistic is t = [Select]
Using an alpha level of 0.05, the researcher would [Select] the null
hypothesis, concluding that there is [Select] difference between single and
married individuals.
