The tables show linear functions representing the estimated time it takes for the math and language arts portions of standardize
d tests with different numbers of questions.
Which function has the greater slope and what does it indicate?
-The math function has the greater slope, which shows that the estimated time per question for math is less than the estimated time per question for language arts.
-The math function has the greater slope, which shows that the estimated time per question for math is greater than the estimated time per question for language arts.
-The language arts function has the greater slope, which shows that the estimated time per question for language arts is less than the estimated time per question for math.
-The language arts function has the greater slope, which shows that the estimated time per question for language arts is greater than the estimated time per question for math.

If ages are normally distributed then using a significance level of 0.05 , we can claim that the population mean is greater than 24.
Given sample mean of 25 years , sample size of 16 ,standard deviation of 2 years.
We have to find whether the population average is greater than 24.
We have to use t test because n is less than 30. It is right tailed.
We have to first form Hypothesis.
:μ>24,
:μ<24.
t=X-μ/S/
t critical at 5% significance level and degree of freedom=15 (16-1)=1.7531
t=24-25/2/
=-1/0.5
=-2
Because 1.7531 is greater than -2 so we will accept the null hypothesis.
Hence we can say that the average of population is greater than 24.
