Question

i need help understanding how to do these

SECTION 7.2 - Applications of the Normal Distribution e Exercises: Use Table V to obtain the areas under the standard normal curve. Sketch a standard normal curve and shade the art of interest in each problem. Determine the area under the standard normal curve that lies to the left of -1.58. 2) Determine the area under the standard normal curve that lies to the left of 2.12. Determine the area under the standard normal curve that lies to the right of 0.79. Determine the area under the standard normal curve that lies to the right of -1.4. 5) Determine the area under the standard normal curve that lies between-1.58 and 2.41.
