Answer:
The correct option is d.
Step-by-step explanation:
The directional hypothesis is:
![H_{a}:\mu>\mu_{0}](https://tex.z-dn.net/?f=H_%7Ba%7D%3A%5Cmu%3E%5Cmu_%7B0%7D)
The sample size is, <em>n</em> = 40.
The significance level is:
![\alpha =1-0.95=0.05](https://tex.z-dn.net/?f=%5Calpha%20%3D1-0.95%3D0.05)
Use the t-table to compute the right-tailed t-critical value as follows:
![t_{\alpha,\ (n-1)}=t_{0.05, (40-1)}](https://tex.z-dn.net/?f=t_%7B%5Calpha%2C%5C%20%28n-1%29%7D%3Dt_%7B0.05%2C%20%2840-1%29%7D)
![=t_{0.05, 39}\\\\\approx t_{0.05, 40}\\\\=1.684\\\\\approx 1.685](https://tex.z-dn.net/?f=%3Dt_%7B0.05%2C%2039%7D%5C%5C%5C%5C%5Capprox%20t_%7B0.05%2C%2040%7D%5C%5C%5C%5C%3D1.684%5C%5C%5C%5C%5Capprox%201.685)
The value is positive since the directional hypothesis suggests that the test is right tailed.
The correct option is d.
