Question

Standard Normal Distribution Table

a. What is the probability that none of them will experience cost-related nonadherence?
P( None )P( None ) =

Round to 3 significant digits.

b. What is the probability that between 12% and 15% will experience cost-related nonadherence?
P(0.12 <  p̂  < 0.15)P(0.12 <  p̂  < 0.15) =

c. What is the probability that more than 20% of them will experience cost-related nonadherence?
P( p̂  > 0.20)P( p̂  > 0.20) =

d. Within what range of values will the proportion of those 60 patients who experience cost-related nonadherence be 95% likely to fall?

  < p̂ <  < p̂ <  

Round to 3 decimal places.

Please provide correct answers. thanks.
