The correct answer is C

The t-statistic for testing the null hypothesis H0:  βi = 0 is t = (bi ? 0) / σi, where βi is the population parameter for independent variable i, bi is the estimated parameter, and σi is the parameter’s standard error.  Using the information provided, the estimated intercept can be computed as b0 = t × σ0 = ?5.2 × 0.55 = ?2.86.
