Answer:
92.65 % light bulbs last less than 2080 hours
Step-by-step explanation:
We are given that The amount of time a certain brand of light bulb lasts is normally distributed
Mean =
Standard deviation =
We are supposed to find What percentage light bulbs last less than 2080 hours, to the nearest tenth

Z=1.45
Refer the z table for p value
p value = 0.9265
Hence 92.65 % light bulbs last less than 2080 hours
x is your starting running time. 1/10 of a minute is 6 seconds, so you can do x - 6(6). 6 times 6 = 36, so your answer is x - 36 seconds. 36 seconds.
Answer: See description below.
The residuals are the differences between the predicted values and the actual values. You will need to make a scatter plot of each difference.
Here are the five points that you will need to plot:
20 - 21 = -1 (1, -1)
17 - 16 = 1 (2, 1)
9 - 10 = -1 (4, -1)
6 - 5 = 1 (5, 1)
2 - 2 = 0 (6, 0)
