Answer:
0.67
Step-by-step explanation:
z = (x-μ)/σ, where
x is the raw score = 5.6 seconds
μ is the population mean = 5.2 seconds
σ is the population standard deviation = 0.3 seconds
z = 5.6 - 5.2/0.3
z = 0.66667
z score is approximately 0.67
The z-score for a player who runs a time of 5.6 seconds is 0.67
In 100 she can make 10 and in 70 she can make 7 so just add 10 and 7 to get the answer of 17
