Steps in Hypothesis Testing: Videos & Practice Problems

i) $H_0:\tau =6$; $H_a:\tau >6$

ii) Fail to reject $H_0$. At the $5\%$ significance level, there is sufficient evidence to conclude that the bakery’s median baking time exceeds $6$ minutes.

i) $H_0:\tau =6$; $H_a:\tau \ne 6$

ii) Reject $H_0$. At the $5\%$ significance level, there is sufficient evidence to conclude that the bakery’s median baking time differs from $6$ minutes.

i) $H_0:\tau =6$; $H_a:\tau \ne 6$

ii) Fail to reject $H_0$. At the $5\%$ significance level, there is not enough evidence to conclude that the bakery’s median baking time differs from $6$ minutes.

i) $H_0:\tau =6$;

ii) Fail to reject $H_0$. At the $5\%$ significance level, there is sufficient evidence to conclude that the bakery’s median baking time is less than $6$ minutes.
