Hope this helps. :)
Answer:
0.26599
Step-by-step explanation:
When given a random number of samples, we solve using this z score formula
z = (x-μ)/σ/√n
where x is the raw score = 268
μ is the population mean = 266
σ is the population standard deviation = 16
n = 25
For x > 268
z = 268 - 266/16/√25
z= 2/16/5
z = 0.625
Probability value from Z-Table:
P(x<268) = 0.73401
P(x>268) = 1 - P(x<268)
P(x>268) = 1 - 0.73401
P(x>268) = 0.26599
The probability that the average pregnancy length of the women in the study is more than 268 days is 0.26599
3.14 is how you write it in decimal form for the calculator
