(h0: = 47) If i reject the null hypothesis, i need a claim to accept; the alternate hypothesis. Alternate hypothesis is that < 47. (h1: < 47) Left tailed: if h1 states that the parameter is less than the value claimed in h0. Right tailed: if h1 states that the parameter is more than the value claimed in h0. Two tailed: if h1 states that the parameter is different than the value claimed in h0. The vet takes rosie"s pulse 6 times in 6 weeks. x = 105bpm. P(x < 105) = p(z < -2. 04) = 0. 0207 = 2%
