describe type i and type ii errors for a hypothesis test of the indicated claim. an urban planner claims that the noontime mean traffic flow rate on a busy downtown college campus street is 38 cars per minute. describe the type i error. choose the correct answer. a. a type i error will occur when the actual noontime mean traffic flow rate is 38 cars per minute, but you fail to reject $h_0:mu = 38$. b. a type i error will occur when the actual noontime mean traffic flow rate is 38 cars per minute, but you reject $h_0:mu = 38$. c. a type i error will occur when the actual noontime mean traffic flow rate is not 38 cars per minute, but you reject $h_0:mu\neq38$. d. a type i error will occur when the actual noontime mean traffic flow rate is not 38 cars per minute, but you fail to reject $h_0:mu\neq38$.

Answer

Brief Explanations:

A Type - I error occurs when the null hypothesis ($H_0$) is true, but we reject it. Here, the null hypothesis is $H_0:\mu = 38$ (where $\mu$ is the noontime mean traffic - flow rate). So a Type - I error will happen when the actual noontime mean traffic flow rate is 38 cars per minute (i.e., $H_0$ is true), but we reject $H_0$.

Answer:

B. A type I error will occur when the actual noontime mean traffic flow rate is 38 cars per minute, but you reject $H_0:\mu = 38$.
