Transcribed Image Text:(c) Choose the appropriate hypotheses and decision rule for a right-tailed t-test for zero slope at \( \alpha = 0.05 \).
a. \( H_0: \beta_1 \leq 0 \) versus \( H_1: \beta_1 > 0 \). Reject the null hypothesis if \( t_{calc} < 1.697 \)
b. \( H_0: \beta_1 \leq 0 \) versus \( H_1: \beta_1 > 0 \). Reject the null hypothesis if \( t_{calc} > 1.697 \)
- \( \bigcirc \) a
- \( \bigcirc \) b
(d-1) Find the \( p \)-value and the \( t \) statistic for the slope. *(Round your answers to 4 decimal places. Leave no cells blank - be certain to enter "0" whenever required.)*

(d-2) We reject the null hypothesis.
- \( \bigcirc \) Yes
- \( \bigcirc \) No
