Answer:
0.0323 = 3.23%. Is unusual
Step-by-step explanation:
Using the normal distribution we can find z value with the mean and standard deviation as follows. x is the value we want to know its probability
z = (x - mean)/standard deviation
z = (5-8.54)/1.91
z = -1.85
Using z tables for normal distribution, for z = 1.85, we have an area under the curve of 0.9677. Since we want to know the probability for 5 minutes or less, we have to substract from
p = 1- 0.9677
p = 0.0323
An event with a probability less than 5% is considered unusual.
I'd say an outlier. P is separated noticably from the other points and would not considerably affect the slope of the line
12*2=24
24*3=72
72*4=288
n*(x+1)
288*(4+1)
288*5=1440
Answer:
437.4m
Step-by-step explanation:
1 cm = 4.5m
7.2x4.5=32.4
3x4.5=13.5
32.4x13.5 = 437.4m
