Answer:
Step-by-step explanation:
Given mean = 84,
Standard deviation = 2,
Sample 64,
95% confidence interval: z = 1.96
Applying empirical rule , means that 95% of data fall within two standard deviations.
ME = = 0.49
Rounding this to 0.5
CI = 83.5< mean < 84.5
Outside of this range= x ≤ 83.5 and ≥ 84.5
2 times 108 is 216
3 times 72 is 216
4 times 54 is 216
6 times 36 is 216
Answer:
Open circle. Points right
Step-by-step explanation:
