Consider a binomial distribution. About 61% of all Salinas residents own a smart phone. Find the mean number of residents own a smart phone when selecting a sample of n = 53 residents.
An Internet service provider is interested in testing to see if there is a difference in the mean weekly connect time for users who come into the service through a dial-up line, DSL, or cable Internet. To test this, the ISP has selected random samples from each category of user and recorded the connect time during a week period. The following data were collected. Click the icon to view the ISP data. Assuming that the test is to be conducted at a 0.01 level of significance, what would the critical value be for this test?

Use the three-read strategy to understand the following exercise from a statistics textbook, and then proceed to complete the exercise. A popular urban legend is that more babies than usual are born during certain phases of the lunar cycle, especially near the full moon. Suppose that a certain paper classified births according to the lunar cycle. Data for a sample of randomly selected births, consistent with summary quantities in the paper, are given in the accompanying table. Lunar Phase Numberof Days Numberof Births New Moon 24 7,670 Waxing Crescent 152 48,442 First Quarter 24 7,589 Waxing Gibbous 149 47,814 Full Moon 24 7,711 Waning Gibbous 150 47,595 Last Quarter 24 7,733 Waning Crescent 152 48,240 Calculate the value of the Χ2 goodness-of-fit test statistic that could be used to determine if the distribution of number of births in each lunar phase is what would be expected based on the number of days in each phase. Use the value of the test statistic to…
In each of the following settings, decide whether you should use two-sample z procedures for a difference in proportions, two- sample t procedures for a difference in means, or paired t procedures for a mean difference. (a) A city planner is comparing traffic patterns at two different intersections. He randomly selects 12 times between 6:00 a.m. and 10:00 p.m., and he and his assistant count the number of cars passing through each intersection during the 10- minute interval that begins at that time.

Read the following passage and observe the word length of each word. Make a frequency distribution of word length. Pargraph: “Statistics play an intrinsic role in computer science and vice versa. Statistics is used for data mining, speech recognition, vision and image analysis, data compression, artificial intelligence, and network and traffic modeling. A statistical background is essential for understanding algorithms and statistical properties that form the backbone of computer science. Typically, statistical approach to models tends to involve stochastic (random) models with prior knowledge of the data. The computer science approach, on the other hand, leans more to algorithmic models without prior knowledge of the data. Ultimately, these come together in attempts to solve problems.” Note table should neat and clean
The college board reported the following mean scores for the three parts of the SAT( The world Almanac, 2009); Critical reading 502 Mathematics 515 Writing 494 Assume the population standard deviation on each part of the test is 100. a. What is the probability that a random sample of 90 test taken will provide a sample mean test score within 10 points of the population mean of 502 on the critical reading part of the test? b) What is the probability that a random sample of 90 test takers will provide a sample mean test score within 10 points of the population mean of 515 on the Mathematics part of the test? Compare this probability to the value computed in part (a)

It is common to think that the more education anindividual receives, the higher the person's income is likely to be. Does this idea translate to states? The following data represent the percentage of the population that has at least a bachelor s degree and the per capita personal income for a random sample of states. Test the claim that states with a higher percentage of the population with at least a bachelor's degree have a higher per capita personal income at the 0.05 level of significance.
