Question

4) With 15 observations, 4a) the smallest of the standard normal quantile values covers an area under the normal curve of ___ /16 = ____ . The corresponding Z-value is -1.53. 4b) The largest of the standard normal quantile values covers an area under the normal curve of ___ /16 = ____ . The corresponding Z-value is +1.53. 4c) The middle of the standard quantile values covers an area under the normal curve of ___ /16 = _____ . The corresponding Z-value is 0.00. See text p. 216 - 217 for information on the normal probability plot.

Explanation / Answer

4a) the smallest of the standard normal quantile values covers an area under the normal curve of 1 /16 = 0.0625 . The corresponding Z-value is -1.53. 4b) The largest of the standard normal quantile values covers an area under the normal curve of 15 /16 = 0.9375 . The corresponding Z-value is +1.53. 4c) The middle of the standard quantile values covers an area under the normal curve of 8 /16 = 0.50 .The corresponding Z-value is 0.00.
