Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.

Question

Many delivery trucks feature a "How Am I Driving?" sticker on the rear bumper, along with a phone number. This
sticker allows drivers to report erratic driving by the truck driver or offer a compliment if they like. A dispatcher at the
trucking station accepts calls and records information from those who call the phone number. The dispatcher reports
that in the past month, 218 calls were received. Of those calls, 178 reported negative driving behaviors by the truck
drivers. How might this data-collection method produce bias in obtaining an estimate of all drivers who are satisfied
with the company's truck drivers?
This sample may lead to nonresponse bias because many drivers may not call the phone number.
O This sample may lead to undercoverage bias because some drivers will be more likely to be included in the sample.
The sample may lead to response bias because some who call the phone number may not provide a truthful opinion.
O This sample may lead to voluntary response bias because drivers can choose to call the phone number and register
an opinion.

Suppose you are the manager of two beachfront hotels : The Palms and Golden Sands. You'd like to know if there is a difference in guest satisfaction between the two hotels. To investigate this, you conduct a survey and ask guests upon departure if they are likely to return to the hotel in the future. For The Palms, 163 out of 227 guests who were surveyed responded " yes ". For Golden Sands, 154 out of 262 guests responded "yes ". Answer the following questions. Round any numbers in your final answers to 2 decimals. 1) Calculate a 95 % confidence interval for the difference in satisfaction rates between The Palms and Golden Sands (Show work) 2) Use the critical value approach to test, at a 1% significance level, whether or not the guest satisfaction rates are different between the two hotels. What do you conclude ? (In your answer, show the steps involved with testing) 3) What is the p-value of your test in part 2?
