A certain test preparation course is designed to help students improve their scores on the LSAT exam. A mock exam is given at th
nasty-shy [4]

Answer:

(9.6, 25.7) is a 80% confidence interval for the average net change in a student's score after completing the course.

Step-by-step explanation:

We have n = 6, \bar{x} =  17.6667 and s = 13.3367. The confidence interval is given by

\bar{x}\pm t_{\alpha/2}(\frac{s}{\sqrt{n}}) where t_{\alpha/2} is the \alpha/2th quantile of the t distribution with n-1=5 degrees of freedom. As we want the 80% confidence interval, we have that \alpha = 0.2 and the confidence interval is 17.6667\pm t_{0.1}(\frac{13.3367}{\sqrt{6}}) where t_{0.1} is the 10th quantile of the t distribution with 5 df, i.e., t_{0.1} = -1.4759. Then, we have 17.6667\pm (1.4759)(\frac{13.3367}{\sqrt{6}}) and the 80% confidence interval is given by (9.6, 25.7)

A pet shop sells goldfish for $ 9 per dozen. How much would 6 goldfish cost? How many goldfish could you buy with $50?
deff fn [24]

Answer:

6 goldfish = $4.50. You can buy 66 goldfish with $50

Step-by-step explanation:

We know that dozen is 12, so 12 goldfish would be $9. To find how much one goldfish costs we would divide 9 and 12. 9÷12 is 0.75. So one goldfish is $0.75.

To find 6 goldfish just multiply 0.75 to 6. 6 goldfish would be $4.50.

We know that 0.75 times 100 would be 75 so you can only buy less than 100 goldfishes. You can buy 66 goldfishes with $50.

If this helped, I would appreciate it if you marked me brainliest. Have a nice day!
