The researchers want to determine
if there is a significant difference
between the academic
performance
of male and female in Statistics.
They surveyed 6 male and 10
female with an average or mean of
89.5
and 93.6 respectively. The
variances are 30.2 and 45
respectively. Is there a significant
difference? Use t
test for two samples to answer this
problem.
A population has SS- 100 and variance, o-4. What is the value of x- jal for the population?
O 100
O 400
O 25
A manager believes that the variance of output on the second shift is greater than the variance on the day shift. The following data are collected:
50 samples on the day shift; variance = 500
40 samples on the second shift; variance = 900
Set up hypotheses
Perform a test and state your conclusions.
