Chapter 9: Q.11 (page 505)

The mean price of mid-sized cars in a region is $32,000. A test is conducted to see if the claim is true. State the Type I and Type II errors in complete sentences.

Short Answer

Expert verified

Type I error : Rejection of the null hypothesis even if it's correct.

Type II error : No rejection of the alternative hypothesis even if it's false.

Step by step solution

01

introduction

Given,

The mean price of mid-sized cars in a region is$32,000.

02

explanation

In the case of the null hypothesis we have,

H0:渭=$32,000which implies the mean price of the of mid-sized cars in a region is$32,000.

In the case of the alternative hypothesis we have,

H1:渭鈮�$32,000which implies the mean price of the of mid-sized cars in a region is not $32,000.

Hence we get,

Type I error : Rejection of the null hypothesis even if it's correct.

Type II error : No rejection of the alternative hypothesis even if it's false.

Sixty-eight percent of online courses taught at community colleges nationwide were taught by full-time faculty. To test if 68% also represents California鈥檚 percent for full-time faculty teaching the online classes, Long Beach City College (LBCC) in California, was randomly selected for comparison. In the same year, 34 of the 44 online courses LBCC offered were taught by full-time faculty. Conduct a hypothesis test to determine if 68% represents California. NOTE: For more accurate results, use more California community colleges and this past year's data.

An article in the San Jose Mercury News stated that students in the California state university system take 4.5 years, on

"Red tide" is a bloom of poison-producing algae-a few different species of a class of plankton called dinoflagellates. When the weather and water conditions cause these blooms, shellfish such as clams living in the area develop dangerous levels of a paralysis-inducing toxin. In Massachusetts, the Division of Marine Fisheries (DMF) monitors levels of the toxin in shellfish by regular sampling of shellfish along the coastline. If the mean level of toxin in clams exceeds 800渭驳(micrograms) of toxin per kg of clam meat in any area, clam harvesting is banned there until the bloom is over and levels of toxin in clams subside. Describe both a TypeI and a Type IIerror in this context, and state which error has the greater consequence.
