If a sample size is less than the sample size must come from a population having a normal distribution in order to follow normal distribution calculations.

If a sample size is less than ___30, the sample size must come from a population having a normal distribution in order to follow normal distribution calculations.

Step-by-step explanation:

By Central Limit Theorem we know that if we have a population with mean μ and standard deviation σ, also for sufficiently large sample size, sample distribution is approximately Normally distributed i.e. the population is normal then this theorem is true even for sample size less than 30.

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this
