Answer:
A. T > 2.539
Step-by-step explanation:
We have a hypothesis test of the mean, with unknown population standard deviation.
The hypothesis are:
From the hypothesis we can see that the test is right-tailed, so the critical value of t should be a positive value.
The degrees of freedom can be calculated as:
The significance level is 0.01, so the critical value tc should be the one that satisfies:
Looking up in a t-table, for 19 degrees of freedom, this critical value is tc=2.539.
Answer:
Step-by-step explanation:
(-4, -1) is what you asked to be plotted.
The first number is what number you go to on the x axis (horizontal).
The second number is what number you go to on the y axis (vertical).
I've attached a picture to help demonstrate. :)
The way I remember which comes first is to keep it alphabetical. X comes first, so go on the x axis first, then y
