In this question, calculate the probability using Rguroo, then choose "Graph" to see the graph of the shaded area in the normal distribution. Save the graph on your device , then upload (insert) your finalized graph in the box below. To find percentiles, you need to use the inverse probability, check below: Example: P(W
In this question, calculate the probability using Rguroo, then choose "Graph" to see the graph of the shaded area in the normal distribution. Save the graph on your device , then upload (insert) your finalized graph in the box below.
To find percentiles, you need to use the inverse probability, check below:
Example: P(W<w)=0.20 means the 20th percentile of baby weights which in the display below shows that weightsw=9.2276lbs. is at the 20th percentile.
For find the middle (between) two unknown values with a certain percentile check the example below:
Example: If we want the the two baby weights that correspond to the middle 40 percent of weights
P(w1<W<w2)=0.40
W: the weight of male babies less than two months old in the US is
a) Find the 81st percentile of the baby weights. P(W<w)=0.81
b) Find the probability that a randomly chosen baby weighs between 10 and 11 pounds.
