ALL I NEED TO GO WITH THIS IS A TREND LINE SLOPE THIS IS MY 3RD REQUEST.
On March 1st the stock price was: $28.41 (Pi)
On April 1st the stock price was: $28.91 (Pf)
The slope is defined as:
The trend predicts that the stock price will increase 0.5 dollars every month.
Therefore we expect the stock price on the first day of trading in May to be:
On May 3rd (The first trading day in May) the price was $27.76 which was below the predicted price.
In general, one can say that the trend predicts a behavior like:
Where PMarch is the price on March 1st and n is the number of months after March (for example for May n=2)
So for June (n=3) the prediction is:
While the actual price was $26.47

- "Your solution, looks excellent. I recognize things from previous chapters. I have seen the standard deviation formula you used to get 5.154. I do understand the Central Limit Theorem needs the sample size (n) to be greater than 30, we have 100. I do understand the sample mean(s) of the population will follow a normal distribution, and that CLT states the sample mean of population is the population (mean), we have 143.74. But when and WHY do we use the standard deviation formula where you got 5.154. WHEN & Why use standard deviation of the sample mean. I don't understand, why don't we simply use the "100" I understand that standard deviation is the square root of variance. I do understand that the variance is the square of the differences of each sample data value minus the mean. But somehow, why not use 100, why use standard deviation of sample mean? Please help explain."
