, It has been hypothesised that the probability of having an asthma attack on a particular day may vary across the days of the week.Baibergenov et al. (2005) report a longitudinal study in which the number of emergency department admissions due to asthma were recordedin Ontario between April 2001 and March 2004. Suppose the data were as in the table below:Day of attackTues Wed Thur FriSunMonSatNumber recorded 15456 13811 13228 12786 12446 14228 16837Baibergenova, A., Thabane, L., Akhtar-Danesh, N., Levine, M., Gafni, A., Moineddin, R. and Pulcins, I.

A boxplot Part b)Which of the following best describes the null hypothesis?A. The probability of having an asthma attack in Ontario on a particular day varies across the days of the week.B. The number of asthma attacks in Ontario per day varies by day of the week.C. The probability of having an asthma attack in Ontario on a particular day does not vary across the days of the week.D. There is no variation in the daily number of asthma attacks in Ontario.E. The mean number of asthma attacks in Ontario per day varies by day of the week.Part c)Under the null hypothesis, what would be the expected number of emergency admissions due to asthma in Ontario on a Tuesday?Give your answer to 2 decimal places.Part d)Compute your test statistic here using R, giving your answer to 2 decimal places.Part e)Provide the P-value of your test to 3 decimal places.

Are birthdays "evenly distributed" throughout the year, or are they more common during some parts of the year than others? Owners of a children's toy store chain asked this question. Some data collected by the chain are summarized in the table below. The data were obtained from a random sample of 180 people. The birthdate of each person was recorded, and each of these dates was placed into one of four categories: winter (December 21-March 20), spring (March 21-June 20), summer (June 21-September 20), and fall (September 21-December 20). The numbers in the first row of the table are the frequencies observed in the sample for these season categories. The numbers in the second row are the expected frequencies under the assumption that birthdays are equally likely during each season of the year. The bottom row of numbers gives the following value for each of the season categories. (Each expert I have asked has gotten the critical value wrong so I added a picture of the correct formula to…
A student selects a random sample of 145 students from her large high school. For each student, she records the grade level and their favorite type of pet. She would like to know if there is convincing evidence that grade level is associated with type of pet. Let a = 0.05. The observed and expected counts are displayed in the tables. Observed counts: Pet Dog Cat Bird Other Ninth and Tenth 21 15 8 30 Grades Eleventh and Grade 24 12 11 24 Twelfth Grades Expected counts: Pet Dog Cat Bird Other Ninth and Tenth 23.0 13.8 9.7 27.6 Grades Grade
Are birthdays "evenly distributed" throughout the year, or are they more common during some parts of the year than others? Owners of a children's toy store chain in the Northwest asked just this question. Some data collected by the chain are summarized in the table below. The data were obtained from a random sample of 190 people. The birthdate of each person was recorded, and each of these dates was placed into one of four categories: winter (December 21-March 20), spring (March 21-June 20), summer (June 21-September 20), and fall (September 21-December 20). The numbers in the first row of the table are the frequencies observed in the sample for these season categories. The numbers in the second row are the expected frequencies under the assumption that birthdays are equally likely during each season of the year.

A warehouse manager wants to know if there is an association between the shift worked and being on time for work. To investigate, he selects a random sample of 70 workers and classifies each one according to the shift they worked most recently and whether they were on time for work. He was unable to classify a substantial number of people as being on time, so he classified those individuals as unknown. The data are displayed in the table. The manager would like to know if these data provide convincing evidence of an association between the shift worked and being on time in the large population of all workers at this warehouse. The random and 10% conditions are met. Is the Large Counts condition met? Yes, the smallest expected count is 5, so all expected counts are at least 5. Yes, the smallest expected count is 8.54, so all expected counts are at least 5. No, the smallest expected count is 2.56, so the expected counts are not all at least 5. No, the smallest expected count is…
An article about the California lattery gave the following information on the age distribution of adults in California: 35% are between 18 and 34 years old, 51% are between 35 and 64 years old, and 14% are 65 years old or older. The artide also gave Information on the age distribution of those who purchase lottery tickets. The following table is consistent with the values given in the article. Suppose that the data resulted from a random sample of 200 lattery ticket purchasers. Based on these sample data, is it reasonable to condude that ane or more af these three age groups buys a disproportionate share of lottery tickets? Use a chi-square goodness-of-fit test with a- 0.05. (Round your answer to two decimal places.) Age of Purchaser Frequency 18-34 45 35-64 100 65 and over 55 P-value interval Op

It is also known that both populations are approximately normally distributed. Construct a 90% confidence interval for the difference between the mean annual income of teachers from Georgia (,) and the mean annual income of teachers from Indiana (₂). Then find the lower limit and upper…
Consider the population of car drivers in the United States, and how many traffic tickets they've each received over the course of their lives. Would the distribution of these traffic tickets be left-skewed (where we often see mean median)? Pick ONE option Left-skewed Right-skewed It would be unreasonable to guess Potentially both at once
