Personnel tests are designed to test a job applicant's cognitive and/or physical abilities. A particular dexterity test is administered nationwide by a private testing service. It is known that for all tests administered last year, the distribution of scores was approximately normal with mean 73 and standard deviation 7.7. a.

The testing service reported to a particular employer that one of its job candidate's scores fell at the 98th percentile of the distribution (i.e., approximately 98% of the scores were lower than the candidate's, and only 2% were higher). What was the candidate's score? Click here to view a table of areas under the standardized normal curve. a. Approximately % of the test scores during the past year exceeded 79. (Round to one decimal place as needed.) b. The candidate's score was (Round to the nearest whole number as needed.)
