Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol ( mu μ, p, sigma σ) for

ella [17]

Answer:

Null hypothesis: $H_0:\; \mu = 48\; ^\circ\rm F$ .

Alternative hypothesis: $H_1:\; \mu \ne 48\; \rm ^\circ F$ .

Step-by-step explanation:

In hypothesis testing, the alternative hypothesis $H_1$ represents the claim that is being tested. According to the claim in this question, the true (population) mean $\mu$ is "incorrect," or not equal to (" $\ne$ ") the proposed value of $48\; \rm ^\circ F$ . Hence, the alternative hypothesis for this question would be $H_0:\; \mu \ne 48\; \rm ^\circ F$ .

On the other hand, the null hypothesis represents what happens when that claim is disproved; it should always use the equal sign (" $=$ ".) In this question, that's the same as saying that the (population) mean $\mu$ is indeed equal to $48\; \rm ^\circ F$ . Hence, the null hypothesis for this question would be: $H_1:\; \mu = 48\; \rm ^\circ F$ .
