Answer:

Interval for t statistic = (-1.345, 1.345)

Step-by-step explanation:

given that a random sample of size 15 is selected from a normal population. The population standard deviation is unknown.

Since population std deviation is unknown and also sample size <30, we have to use t test only for testing of hypothesis

Given it is a two tailed test at 10% significance level.

Degree of freedom = 15-1 =14

t critical value for df 14 two tailed is

1.345

Hence our test statistic should lie between

(-1.345, 1.345)

Then null hypothesis is accepted

Other wise it is rejected.

Answer:

4

Step-by-step explanation:

The y-coordinate of the point where both lines intersect will give us the same solution for x.

At y = 4, both equations will have a corresponding x-value of 1.

Therefore, the value of y that that will make both equations have the same solution of x is 4.

Answer:

f(5) = -2

Step-by-step explanation:

You look on the x-axis for 5 because f(5) means let x = 5. Then go down to the graph (the red zig-zaggy line) At the red line (you're still directly under the 5) look over to the y-axis to find the value. That's your answer. It is -2. The point (5, -2) is on the red graph.

f(5) = -2
