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
1) order them from least to greatest. (0.2, 0.3, 0.4, 0.7, 0.9, 0.9)
2) Take the largest number and smallest number and find the difference. 0.9-0.2=0.7
3) answer is 0.7
Answer:
49/72
Step-by-step explanation:
I would say the answer is b, because it is a rhombus gape and all sides are congruent and there are 4 sides
