O A probability is always negative A probability must be between zero and one O A probability is always be a rational number O A probability must be an integer D Question 4 1 pts A sampling technique that uses a simple random sample from the entire population is known as O Cluster Sampling Systematic Sampling O Convenience Sampling O Random SamplingD Question 5 1 pts Home Announcements A sampling technique that creates a sample by using data from population members that are readily available is known as_ _ _ Assignments Simple Syllabus Multistage sampling Discussions Convenience Sampling Grades O Random Sampling Pages O Cluster Sampling Files Quizzes Modules D Question 6 1 pts Collaborations What does a standard score measure? Chat My Credentials The number of standard deviations that are present under a normal curve Office 365 The number of standard deviations a measurement is from the highest value Portfolium The number of standard deviations a measurement is from the mean. Class Climate O The number of standard deviations a measurement is from the lowest value Surveys Library Resources Cisco Webex D Question 7 1 pts BryteWave Course Materials Follett Discover Which type of data can be shown in a Histogram? O Qualitative/Categorical Quantitative and Qualitative O Categorical Quantitative D Question 8 1 pts A data set has values ranging from a low of 10 to a high of 50. What is wrong with using the class limits 10-20, 20-30, 30-40, 40-50 for a frequency table? O Each data value must fall into one class. Some data values do not have a class All the answers above O There is nothing wrong with using these class limits for the data set. The classes overlap so that some data values, such as 40, fall within two classes2022 Fall Session D Question 9 2 pts Home Announcements What symbol is used for the arithmetic mean when it is a sample statistic? What symbol is used when the arithmetic mean is a population parameter? count Assignments sample statistic, A; population parameter, x Simple Syllabus sample statistic, x : population parameter, x board Discussions O sample statistic, A; population parameter, u urses Grades sample statistic, x : population parameter, u Pages endar Files Quizzes D Question 10 2 pts Modules Collaborations Over the past 55 years, there has been a strong negative correlation between average annual income and the number of traffic accidents. In other words, average annual incomes have been rising while traffic accidents have been decreasing. Do you think story the increase in the average annual incomes is the cause of less traffic accidents? Explain. Chat Help My Credentials O Yes. A strong correlation implies causation. Office 365 O No. A strong correlation implies causation. Portfolium Yes. A strong correlation does not imply causation. Class Climate O No. A strong correlation does not imply causation.

What is the complement of the event "rain today"? O rain yesterday O no rain today no rain tomorrow O rain tomorrow D Question 12 2 pts What is the law of large numbers? O As the sample size decreases, the relative frequency of outcomes gets closer to the theoretical probability of the outcome As the sample size increases, the relative frequency of outcomes gets closer to the theoretical probability of the outcome O As the sample size increases, the cumulative frequency of outcomes gets closer to the theoretical probability of the outcome As the sample size increases, the relative frequency of outcomes moves further from the theoretical probability of the outcome
