StatCrunch Activity - Ch. 7

NEATNESS AND LEGIBILITY EXPECTED.

Technology

StatCrunch's Normal Calculator: Stat -> Calculators -> Normal. Use Standard for left-tail or right-tail regions. Use Between for bounded interval regions.

For AREA/PROBABILITY/PROPORTION: Enter z-score(s) and leave the box after = blank For Z-SCORE: Enter area in box after = and leave z-score(s) blank

Standard Normal Distribution Using StatCrunch

Recall: The Standard Normal Distribution has a mean of 0 and a standard deviation is 1.

For each problem, include a shaded sketch of the indicated region. Round result from StatCrunch to6 decimal placesor report listed result of fewer than 6 decimal places given.

1. Determine theareaunder the standard normal curve that lies between Z = -3.07 and Z = 1.69. <2>
