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
Answer: Mean = 204.6 , Median = 195 and mode =195
Step-by-step explanation:
The given data for Winona’s bowling scores for the past nine weeks : 195, 180, 195, 212, 208, 231, 179, 246, 195.
The formula to find Mean is given by :-
For median , first we arrange data values in order as
179, 180, 195, 195, 195, 208, 212, 231, 246
Since the number of data values is 9 (odd).
∴ Median = Middle most data value = 195
Also, Mode = Most occurring data value = 195
