Interpretation
One sample t test indicate relationship between sample mean and population mean and
indicate whether there is significant difference between sample mean and population mean. In
the table given above it can be seen that value of statistics is (M = 1.97, SD = 0.688). This means
that on an average sample unit prefer Dallas Mavericks and standard deviation is very low which
further indicate that majority of respondents prefer mentioned team. Value of level of
significance is 0.069>0.05 which reflect that there is no significant mean difference between
sample mean and population mean. Null hypothesis accepted.
