As a part of her studies, jolyn gathered data on the length of time between dentist visits for a sample of 23 individuals. she works through the testing procedure: h0: μ=187; ha: μ> 187 α=0.05 the test statistic is t0=x¯−μ0sn√=2.266. the critical value is t0.05=1.717. at the 5% significance level, does the data provide sufficient evidence to conclude that the mean length of time between dentist visits is more than 187 days? select the correct answer below:
a. we should reject the null hypothesis because t0 b. we should not reject the null hypothesis because t0 c. we should reject the null hypothesis because t0> tα. so, at the 5% significance level, the data provide sufficient evidence to conclude that the average length of time between dentist visits is greater than 187 days.
d. we should not reject the null hypothesis because t0> tα. so, at the 5% significance level, the data do not provide sufficient evidence to conclude that the average length of time between dentist visits is greater than 187 days.
