1=5-4 because you have to substitute x and y (x,y) or (5,1)
Answer:
2.083 < µ1 - µ2 < 5.917
Step-by-step explanation:
We will need to construct a 90% confidence interval for the difference of 2 means where the populations are normally distributed, and their variances are equal.
The calculations of the sample means and standard deviations are done for us.
Sample 1: Catalyst 1
n = 12, x = 85, s = 4
Sample 2: Catalyst 2
n = 10, x = 81, s = 5
See attached photo for the construction of the confidence interval...
Answer:
1) -120, -240, -360
2) 24 oz
Step-by-step explanation:
1) 24 * 5 = 120 , 24 * 10 = 240, 24 * 15 =360
5 years will be -120, 10 years will be -240, 15 years will be -360
2) 8 * 3 = 24 oz
I hope this helped, please mark Brainliest, thank you!!
