Answer:
d. Reject H0 if t < -1.6604
Step-by-step explanation:
This is a hypothesis test for the population mean.
The claim is that the mean number of tissues used during a cold is significantly less than 60.
Then, the null and alternative hypothesis are:
![H_0: \mu=60\\\\H_a:\mu< 60](https://tex.z-dn.net/?f=H_0%3A%20%5Cmu%3D60%5C%5C%5C%5CH_a%3A%5Cmu%3C%2060)
The significance level is 0.05.
The critical value for a level of significance is α=0.05, a left-tailed test and 99 degrees of freedom is tc=-1.6604.
The decision rule is that if the test statistic is below tc=-1.6604, the null hypothesis is rejected.
