The student gets either six or seven answers correct. The probability the student gets either six or seven answers correct is (Round to four decimal places as needed.) b. The student gets botween two and six answers correct, inclusive. The probability the student gets between two and six answers correct, inclusive is 0.8175 (Round to four decimal places as needed.) c. Approximate the probabilities in parts (a) and (b) by areas under a normal curve. Compare your answers. Select the correct choice below, and, if necessary, fillin the answer box to complete your choice. O A. Using the nomal approximation to the binomial distribution, the probability the student gets either six or seven answers correct is approximately (Round to four decimal places as needed.) O B. The normal approximation to the binomial distribution cannot be used. Select the correct choice below, and, if necessary, fil in the answer box to complote your choice OA Using the normal approximation to the binomial distribution, the probability the student gets between two and six answers correct, inclusive is approximately (Round to four decimal places as needed.) B. The normal approximation to the binomial distribution cannot be used.


Extracted text: Compare your answers. Choose the correct answer below. OA The nomal approximation for part a is approximately equal, while the nomal approximation for part bis not approximately equal to the enact binomial probability B. Both probabilities using the normal approximation are approximately equal to the exact binomial probabilities. OC. Both probabilities using the normal approximation are not within 1% of the exact binomial probabiltes OD. The normal approximation for part a is not approximately equal, while the normal approximation for part b is approximately equal to the exact binomial probability OE. The normal approximation to the binomial distribution cannot be used.
