Answer:
d. No, the conditions for normality have not been met because the sample size for the pennies is not large enough and no information is given about the distributions of the populations.
Step-by-step explanation:
In this example, we learn that the sample taken of pennies was of 25, while the sample of quarters was of 35. According to the central limit theorem, a sample must be equal to or larger than 30 for the theorem to hold. The theorem states that when random variables are added, they tend towards a normal distribution even if the original variables themselves are not normally distributed. In this question, the sample of pennies is not large enough for the theorem to hold. On top of this, we have no information about the distribution of the populations. Therefore, the conditions for normality have not been met.
There can be so many of such.
Eg. 38 750 38 835
38 795
38 820
Any of the numbers above when rounded to the nearest hundred would result in 38 800.
The idea is such that to make sure the 100 digit is 7 and the 10 digit is 5 or more.
Or if the 100 digit is already 8, then the 10 digit must be less than 5
Answer:
(-8) and 3.5 and (3.5)
Step-by-step explanation:
The opposite of (8) is (-8). The opposite of -3.5 is 3.5. The opposite of (-3.5) is (3.5).
