Answer:

Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618
Step-by-step explanation:
Normal with mean 6.88 minutes and
a standard deviation of 0.57 minutes.
Choose a student at random from this group and call his time for the mile Y. Find P(Y<6)


y ≈ normal (μ, σ)
The z score is the value decreased by the mean divided by the standard deviation

Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618
Experimental probability means what the probability is concluded by the experiment / trials / real results
Assuming {Section 3 I 32} , means it landed there 32 times out of 80.
We write this as a fraction:
32/80 , we simplify it:
16/40
8/20 <- notice how i'm just halving until I can't anymore
4/10
2/5 <- the simplest answer
The answer is D) 2/5
485, because the mean means you need to calculate the average. to find the average, you take the smallest number from the data set and the largest number. add the largest number by the smallest number and divide by the set of numbers you added (2). Example: (720+250=970 divided by 2 =485)
