,
• D. 95.45%
,
• E. 99.73%
,
• F. 34.134%
,
• H. 84.134%
Step-by-step explanation:
The empirical rule tells us that:
• Around 68% of scores are within 2 standard deviations of the mean,
,
• Around 95% of scores are within 4 standard deviations of the mean,
,
• Around 99.7% of scores are within 6 standard deviations of the mean.
Part B

Part C: Between 58 and 66
