Answer:
The 90% CI for p is (0.53, 0.83)
Step-by-step explanation:
We have to develop a 90% confidence interval for the proportion of all students at the college that have met with a counselor to develop an educational plan.
We have a sample of size 25, where the sample proportion is:

The critical value of z for a 90% CI is z=1.645.
The margin of error is then:

Then, the lower and upper bound of the confidence interval are:

The 90% CI for p is (0.53, 0.83)
Answer: It will take Damon 6 weeks to save the money he needs to buy the snowboard
Step-by-step explanation:
First, let's see what the problem is giving us:
-The variable X will represent the number of weeks it will take Damon to save the money he needs.
- Damon has $40
- Damon is going to safe $20 weekly
- The snowboard costs $160
Therefor:
Our equation will be: $40 + $20X = $160
Step 1
We need to isolate the variable by subtracting in both sides of the equation 40 in order to maintain the equality.
40 - 40 + 20X = 160 - 40
This will let us with 20X = 120
Step 2
We have to isolate the variable again, but this time (because the variable is being multiplied by 20) we have to divide on both sides of the equation.
20X/20 = 120/20
Therefore: X=6
