swer the following questions below. Illustrate the area referring to using the normal curve. 1. Find the area between z = 1.68 and z = -1.37 2. Find the area to the left of z = 1.98 3. Find the area to the right of z = -2.13

Please find the area under the normal curve for each 1 of these.

Suppose the lengths of human pregnancies are normally distributed with u = 266 days and o = 16 days. Complete parts (a) and (b) below. (a) The figure to the right represents the normal curve with µ = 266 days and o = 16 days. The area to the left of X = 235 is 0.0263. Provide two interpretations of this area. Provide one interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals.) O A. The proportion of human pregnancies that last more than days is O B. The proportion of human pregnancies that last less than days is 235 Provide a second interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals.) O A. The probability that a randomly selected human pregnancy lasts less than days is O B. The probability that a randomly selected human pregnancy lasts more than days is (b) The figure…

Use the table to find the area to the right of t = 1.717 with 22 degrees of freedom. Area to the right Degrees of Freedom 0.20 0.10 0.05 0.025 0.01 0.005 21 0.859 1.323 1.721 2.080 2.518 2.831 22 0.858 1.321 1.717 2.074 2.508 2.819 23 0.858 1.319 1.714 2.069 2.500 2.807 24 0.857 1.318 1.711 2.064 2.492 2.797 25 0.856 1.316 1.708 2.060 2.485 2.787 According to the table, the area to the right of t = 1.717 is Now find the area to the left of t = 1.717, rounding the result to two decimal places. (area to the left of t = 1.717) = 1 – (area to the right oft = 1.717) - = 1 -
