Answer:
<h2>The missing value is 3, and the coordinates are (3,3).</h2>Step-by-step explanation:
The complete question is
Complete the missing value in the solution to the equation. (3, ? )
By given, we know that , because coordinates are written like
.
Then, we replace the given coordinate to find .
Therefore, the missing value is 3, and the coordinates are (3,3).
Answer:
The value of test statistic is -4.1247
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $3.26 a gallon
Sample mean, = $3.19 a gallon
Sample size, n = 32
Sample standard deviation, σ = $0.096
First, we design the null and the alternate hypothesis
We use one-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Thus, the value of test statistic is -4.1247
