I think it would be 8-3, not 7. 8x - 2x + 5x = (8-5)x + 5x

<h2>Answer with explanation:</h2>

Let $\mu$ be the population mean.

Null hypothesis : $H_0:\mu\geq26$

Alternative hypothesis : $H_1:\mu$

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: $t=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

$t=\dfrac{25.2-26}{\dfrac{1}{\sqrt{5}}}\approx-1.79$

Critical t-value for t= $t_{n-1, \alpha}=t_{4,0.06}=1.9712$

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.
