Answer:
The p-value of the test is 0.2.
Step-by-step explanation:
Using the alternative hypothesis that µ ≠ 531, Amy found a t-test statistic of 1.311.
Alternative hypothesis means that e have a two-tailed hypothesis test.
Sample 30 citizens. Amy found a t-test statistic of 1.311.What is the p-value of the test statistic?
Thus, we have a two-tailed test with 30 - 1 = 29 degrees of freedom and t = 1.311. So, using a t-distribution calculator, the p-value of the test is 0.2.
First, find out c
4c=-12, so c=-3
-5c=d, so d=15
You find out how much money Sonja had before she paid by taking the $30 she had left and adding it to the $12.50 she paid. $30.00-$12.50 = $42.50

Answer:
84 dogs
Step-by-step explanation:
We can multiply each of the numbers in the ratio by 12 to see the answer:
cats : dogs = 3 : 7 = 36 : 84
There were 84 dogs in the park.
