Answer:
For a data from population which is not normally distributed, the sample means would be approximately a normal distribution if the sample size (n) is greater than 30
Step-by-step explanation:
For a data from population which is not normally distributed, the sample means would be approximately a normal distribution if the sample size (n) is greater than 30 i.e n ≥ 30 this is because the shape of a sample distribution depends on the sample size. But for normal distribution population, the sample means would be approximately a normal distribution even if the sample size is less than 30;
This is how to solve this
Answer:
168.61
Step-by-step explanation:
C=2*Pi*R
C=2*3.14*26.85

<span>$145 saved in her account.
</span><span>$8 an hour at work.
</span><span>at least $320
