Question

In the equation [grade \( =69.9+2.28 \) " hours_of study], where standard deviations are equal to \( 10.4 \) and \( 0.52 \) respectively for intercept and hours of studies, t-statistic for beta_hours_

Answer 1

The t-statistic for beta_hours can be calculated using the formula:

t = (beta_hours - 0) / standard deviation_hours

In this equation, the standard deviation for hours of study is given as 0.52. However, the question does not provide the value of beta_hours. To calculate the t-statistic, we need to know the value of beta_hours.

Once we have the value of beta_hours, we can substitute it into the formula and calculate the t-statistic.

For example, if beta_hours = 2.5, the calculation would be:

t = (2.5 - 0) / 0.52

t = 2.5 / 0.52

t ≈ 4.81

So, if beta_hours is equal to 2.5, the t-statistic for beta_hours would be approximately 4.81.
