Step-by-step explanation:
We want to find the equation of the line that goes through: !6,-10) and is perpendicular to the line
Let's simplify the equation of the line to get:
The slope of this line is -5.
The perpendicular to this line has a slope of
The equation going through (6,-10) is
We substitute to get;
Expand;
Solution :
To claim to be tested is whether "the mean salary is higher than 48,734".
i.e. μ > 48,734
Therefore the null and the alternative hypothesis are
and
Here, n = 50
s = 3600
We take , α = 0.05
The test statistics t is given by
t = 2.15
Now the ">" sign in the sign indicates that the right tailed test
Now degree of freedom, df = n - 1
= 50 - 1
= 49
Therefore, the p value = 0.02
The observed p value is less than α = 0.05, therefore we reject . Hence the mean salary that the accounting graduates are offered from the university is more than the average salary of 48,734 dollar.
