1. Modelling non-zero count dataCount data is quite often only recorded when at least one event happens (i.e.zero count events are not recorded). For example, the numbers below givethe alcohol units consumed by a certain mathematics professor on the last 13times he went out drinking:163 21 3 39 3 2 1 1 2a) Identify the lower quartile, the median, and the upper quartile in thissample [See Sec 1.3.3 of the notes: the sample p-quantile is X(4)where k = p(n–1)+1];b) Using a calculator, calculate the sample mean and variance of thisdata. How much does the value of 9 in this small sample contribute tothe sample variance?

Given information: The data represents the alcohol units consumed by a certain mathematics professor…

A chocolate store gives out small bags of chocolate to its customers, and each bag does not always have the same number of chocolate. The following table represents a sample of a few bags showing the number chocolate of per bag. Calculate IQR. Chocolate 18-20 21-23 24-26 27-29 30-32 33-35 36-38 39-41 Frequency 2 14 1 6 10 2 5 4
A 2012 study of freely forming groups in bars all over Europe examined the natural behavior of groups. The researchers recorded the group size (number of individuals in the group) of all 501 groups in the study that were naturally laughing. The findings were displayed in the figure below. 300 Number of groups 250 200 O 52 O 2.7 0 2 150 3.5 4 100 50 0 254 2 Enter your answer here The median laughter group size in this study is 168 3 The mean laughter group size in this study is O 100.2 Enter your answer here 52 4 5 Laughter group size 21 6 6 Can we conclude from these findings that, in European bars in 2012, smaller groups were more likely than larger groups to be naturally laughing? Explain your statistical reasoning in one sentence.

You want to examine the relationship between dropping out of high school and delinquency. You have a random sample of 11 students. You have the number of delinquent offenses that each student reported committing in the year before and after dropping out of school. The following table shows the data.

Researchers are wondering whether they can predict college GPA with the number of hours studying per week. To test this, they randomly select 8 college students, record their GPA and the number of hours spent studying per week. ID 1 2 3 4 5 6 7 8 GPA 2.5 2.7 3.4 3.7 2.7 1.9 2.0 4.0 O Reject Hours studying per week 25.0 Based on the information in the table above, the researchers compute the regression equation: Y = -0.970 + 0.125 X. Do the researchers have enough evidence to claim that the number of hours studying predicts students' GPA? Should you reject or fail to reject the null hypothesis? Fail to reject 27.6 30.2 35.0 31.6 25.6 30.0 40.0
The following table indicates the weather changes at a particular location. For example, the day following a clear day, there is a 40% chance that the weather will be clear, a 40% chance that it will be cloudy and a 20% chance that it will be rainy. What is the probability that the weather two days after it rains will be clear? Answer in whole number See attached photo
