,squared value is 0.49. This finding means that
There is not a statistically significant relationship between
the variables
There is a moderate positive relationship between the
variables
2
,The number of minutes of pumping explains 49% of
the variance in milk output
There is not enough information to determine whether
there is a meaningful relationship between the variables -
....ANSWER...The number of minutes pumping explains
49% of the milk output
Parametric tests can be used to analyze ordinal variables
but not nominal variables - ....ANSWER...False
An R-value of 0.33 indicates
A moderate relationship between the variables
A statistically significant relationship between the
variables
the null hypothesis should be rejected

, there is no relationship between the variables -
....ANSWER...A moderate relationship between the
variables
