Answer:
By growing a sample of 10 gardenia bushes in the shade and similarly 10 in full sun.
Step-by-step explanation:
For getting a representative result, the experiment must be done in two different circumstances so that the final results of the two conditions can be compared and condition for better result can be determined.
So, Perry must grow a sample of 10 gardenia bushes in shade and the same number of gardenia bushes i.e. 10 in the full sun. After the plants flower there will be a clear difference in the flowering of both the sample of plants because gardenia bushes flower will in shade than in full sun. So, the average number of flowers will be greater in the shade than in full sun.
Answer:
The minimum sample size needed to be 95% confident that the sample mean is within 4 dollars of the true population mean is 47.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
If the population standard deviation is 14 dollars, what minimum sample size is needed to be 95% confident that the sample mean is within 4 dollars of the true population mean
This is n when . So
The minimum sample size needed to be 95% confident that the sample mean is within 4 dollars of the true population mean is 47.
