Answer:
Step-by-step explanation:
6.81 - 6.79 - 6.69 - 6.59 - 6.65 - 6.60 - 6.74 - 6.70 - 6.76
6.84 - 6.81 - 6.71 - 6.66 - 6.76 - 6.76 - 6.77 - 6.72 - 6.68
7.71 - 6.79 - 6.72 - 6.72 - 6.72 - 6.79 - 6.83

S.D = 0.21

df = 24
α = 0.05
t = 2.064
![I=6.77\pm2.064\times\frac{0.21}{\sqrt{25} } \\\\=6.77\pm0.087\\\\=[6.683,6.857]](https://tex.z-dn.net/?f=I%3D6.77%5Cpm2.064%5Ctimes%5Cfrac%7B0.21%7D%7B%5Csqrt%7B25%7D%20%7D%20%5C%5C%5C%5C%3D6.77%5Cpm0.087%5C%5C%5C%5C%3D%5B6.683%2C6.857%5D)
