8.2.3 (tb 64) According to a national database, 10% of all people living in the United States are left-handed. A high school is remodeling their classrooms and the administrator has to decide how many left-handed desks to buy. A left-handed desk costs slightly more than a right-handed desk, but it is easier for a left-handed student to complete assignments in the proper desk. To test the proportion of left-handed students at the school, the administrator will take a random sample of 150 students. A significance test will be performed using the following hypotheses at the 5% significance level: Ho: p = 0.1 where p is the true proportion of left-handed students at the high school. Ha: p > 0.1 Describe a consequence of a Type I error in this setting.

Opinions are split about a coffee company's pumpkin-flavored coffee (PFC). Yet every year over the last five years the consumption of pumpkin-flavored goods has increased. If we look at the numbers, it also becomes clear why a leading coffee company keeps offering the PFC earlier and earlier every year. According to a magazine, the amount spent by PFC buyers at the coffee company is about 17% higher than non-PFC buyers. The accompanying table shows a random sample of eight consumers, the amount they spend per week, and the number of PFCs purchased per week.

Errors in medical prescriptions occur relatively frequently. In a study, two groups of doctors had similar err rates and one group switched to e-prescriptions while the other continued with hand-written prescriptions. C year later, the number of errors was measured. The results are given in the two-way table. No Error Error 254 Electronic 3594 Written 1478 2370 a). Fill in the row and column totals. b). What proportion of all the prescriptions had errors in them? c). What proportion of electronic prescriptions had errors in them? d). What proportion of written prescriptions had errors in them? e). What proportion of the prescriptions with errors were written prescriptions?
Suppose that in a survey of 1,000 U.S. residents, 721 residents believed that the amount of violent television programming had increased over the past 10 years, 454 residents believed that the overall quality of television programming had decreased over the past 10 years, and 362 residents believed both. What proportion of the 1,000 U.S. residents believed that either the amount of violent programming had increased or the overall quality of programming had decreased over the past 10 years? (Round your answer to 3 decimal places.)
In a statistics activity, students are asked to spin a penny and a dime and determine the proportion of times that each lands with tails up. The students believe that since a dime is lighter, it will have a lower proportion of times landing tails up compared with the penny. The students are instructed to spin the penny and the dime 30 times and record the number of times each lands tails up. For one student, the penny lands tails side up 18 times, and the dime lands tails side up 20 times. Let pp = the true proportion of times a dime will land tails up and pp = the true proportion of times a penny will land tails up. The P-value for this significance test is 0.296. Which of the following is the correct conclusion for this test of the hypotheses H Pp-Pp=0 and H, Po-Pp 0.05. There is sufficient evidence that the true proportion of times a dime will land tails up is significantly less than the penny. O The student should reject the null hypothesis since 0.296 > 0.05. There is insufficient…

There are 64% of US adults who own a smartphone, up from 35% in 2011. Smartphones have become an important way for Americans to communicate, go online, access and share information. The Pew Research Center surveyed 1635 people in November, 2014 on smartphone ownership. Their goal was to learn how Americans use their smartphone devices. Identify the population and the sample.
