Answer: $1.50/cookie
Step-by-step explanation:
Cookies = x
Water = y
5x + y = $8.75
y = 1.25
Plug in y-value into equation:
5x +1.25 = 8.75
5x = 8.75 - 1.25
5x = 7.50
x = 7.50/5
x = $1.50 for 1 cookie.

Answer:
[143.61, 156.39]
Step-by-step explanation:
Because the population standard deviation is not available AND the sample size is less than 31, we can use a t procedure here.
Plug these values into your calculator:
Sample mean = 150
Sample size = 16
Standard deviation = 12
Confidence level = 95% = 0.95
and get [143.61, 156.39] as your confidence interval
