1. A psychiatrist is testing a new anti-anxiety drug, which seems to have the potentially harmful side effect of lowering the heart rate. For a sample of 50 medical students whose pulse was measured after 6 weeks of taking the drug, the mean heart rate was 70 beats per minute (bpm).

Transcribed Image Text:1. A psychiatrist is testing a new anti-anxiety
drug, which seems to have the potentially
harmful side effect of lowering the heart rate.
For a sample of 50 medical students whose
pulse was measured after 6 weeks of taking
the drug, the mean heart rate was 70 beats
per minute (bpm). If the mean heart rate for
the population is 72 bpm with a standard
deviation of 12, can the psychiatrist conclude
that the new drug lowers heart rate
significantly? (Set alpha = .05 and perform a
one-tailed test.)
