Can't figure it out this one all day and it looks easy

e) Is estimated slope value of 1.53 statistically significantly greater than zero? Conduct appropriate hypotheses, calculate an appropriate test statistic, calculate a p-value or critical value and interpret your result in the context of the problem. Use α=0.05.

Here are the known values
A sample of 19 female bears was measured for chest girth (y) and neck girth (x), both in inches. The LS regression equation related the two variables is ŷ=5.32+1.53x
SSE=231.72 sq. inches, r=0.887, SSxx=365.18 sq.inches, and x¯ =18.76 inches
