The claim is that less than 93% of adults have a cell phone, which serves as the null hypothesis (H0: p ≥ 0.93) and the alternative hypothesis (H1: p < 0.93). Given that 85% of 1161 adults in the sample say they own a cell phone, a test statistic can be calculated to evaluate this hypothesis.

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

**Statistical Claim and Test Statistic Calculation**

**Claim:** Fewer than 93% of adults have a cell phone. In a reputable poll of 1161 adults, 85% said that they have a cell phone. Find the value of the test statistic.

**The value of the test statistic is:** [ ]
(Round to two decimal places as needed.)

**Explanation:**
This statement involves using a hypothesis test for a population proportion. The claim is that less than 93% of adults have a cell phone, which serves as the null hypothesis (H0: p ≥ 0.93) and the alternative hypothesis (H1: p < 0.93). Given that 85% of 1161 adults in the sample say they own a cell phone, a test statistic can be calculated to evaluate this hypothesis. The result will be rounded to two decimal places to ensure precision in communication of the statistical findings.
