Function Description

Returns the results of a z test t test applied to two separate series to test if their means are different, under the null hypothesis that the data is normally distributed and that the two series have known variances.

 

The output has 9 rows and 2 columns (ignore second column entry for Rows 4 to 9):

 

-          Row 1: Mean (of series)

-          Row 2: Variance (of series)

-          Row 3: Number of entries in series

-          Row 4: Hypothesized Mean Difference

-          Row 5: z statistic

-          Row 6: P-value of this z statistic (one tail)

-          Row 7: t critical level (one tail), for given confidence level

-          Row 8: P-value of this z statistic (two tail)

-          Row 9: t critical level (two tail), for given confidence level
