Let
be the population mean.
Null hypothesis : ![H_0:\mu\geq26](https://tex.z-dn.net/?f=H_0%3A%5Cmu%5Cgeq26)
Alternative hypothesis : ![H_1:\mu](https://tex.z-dn.net/?f=H_1%3A%5Cmu%3C26)
Since the alternative hypothesis is left tailed, so the test is a left-tailed test.
Sample size : n=5 <30 , so we use t-test.
Test statistic: ![t=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B%5Coverline%7Bx%7D-%5Cmu%7D%7B%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%7D)
![t=\dfrac{25.2-26}{\dfrac{1}{\sqrt{5}}}\approx-1.79](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B25.2-26%7D%7B%5Cdfrac%7B1%7D%7B%5Csqrt%7B5%7D%7D%7D%5Capprox-1.79)
Critical t-value for t=![t_{n-1, \alpha}=t_{4,0.06}=1.9712](https://tex.z-dn.net/?f=t_%7Bn-1%2C%20%5Calpha%7D%3Dt_%7B4%2C0.06%7D%3D1.9712)
Since, the absolute value of t (1.79) is less than the critical t-value , so we fail to reject the null hypothesis.
Hence, we have sufficient evidence to support the company's claim.

Answer:
4/9
Step-by-step explanation:
The probability of getting a card less than 7 is 2/3, and picking a card greater than 5 is 2/3 too, so I believe that now you just have to multiply them: 2/3 * 2/3 = 4/9, and that, I believe, is your answer.
Tell me if I'm wrong :)
