To find the area under the standard normal curve to the left of z=0.49, we need to use a standard normal distribution table or a calculator.
The area to the left of z=0.49 is the same as the area between z=0 and z=0.49. From the standard normal distribution table, we find that the area to the left of z=0.49 is approximately 0.6861.
Next, to find the area under the standard normal curve to the right of z=1.91, we need to find the area between z=1.91 and z=0. Since the total area under the standard normal curve is 1, the area to the right of z=1.91 is 1 - the area to the left of z=1.91.
From the standard normal distribution table, we find that the area to the left of z=1.91 is approximately 0.9713. So the area to the right of z=1.91 is 1 - 0.9713 = 0.0287.
Therefore, the area under the standard normal curve to the left of z=0.49 is approximately 0.6861 and the area to the right of z=1.91 is approximately 0.0287.
