Consider the following statements. (i) The p-value forms the borderline between significance levels that would result in rejecting the null hypothesis and significance levels that would result in not rejecting the null hypothesis. (ii) The p-value is calculated under the assumption that the alternative hypothesis is true. (iii) The smaller the p-value, the stronger the evidence is in favor of the alternative hypothesis. Determine which of the above statements are true (1) or false (2).

The result is different because the formula is dependent on which values are the x values and which values are the y values. The result is the same because the formula is dependent on which values are the x values and which values are the y values.

Serial correlation, also known as autocorrelation, describes the extent to which the result in one period of a time series is related to the result in the next period. A time series with high serial correlation is said to be very predictable from one period to the next. If the serial correlation is low (or near zero), the time series is considered to be much less predictable. For more information about serial correlation, see the book Ibbotson SBBI published by...
