**Activity: Probability and Standard Deviation in Baseball**In this exercise, we will explore probability using the example of the New England Colonials baseball team. You will estimate outcomes and quantify uncertainty using concepts like mean and standard deviation.**Scenario:**Suppose that the New England Colonials baseball team is equally likely to win any particular game as not to win it. We will consider a random sample of 30 Colonials games.**Instructions:**1. **Estimate the Number of Wins:** - Calculate the mean of the relevant distribution to estimate the number of games in the sample that the Colonials win. This mean is the expectation of the relevant random variable. - *Note: Do not round your response.*2. **Quantify Uncertainty:** - Provide the standard deviation of the distribution to quantify the uncertainty of your estimate. - *Note: Round your response to at least three decimal places.*Feel free to consult a list of formulas if necessary, and use the interactive elements provided to input your answers.

2. Which of the following are practical ways to assess normality of the residuals? Select all that apply a. Normal probability plots (the R command is qqnorm() b. Anderson-Darling tests. c. Shapiro-Wilks tests. d. Boxplots e. Just ask if they are normal, or, guess, because, who really cares?
Suppose we take a sample of size 30 from a geometrical distribution 200 times. Draw a graph of the distribution of X¯n, this is a histogram of 200 values of the sample mean. Calculate the expected value and variance of X¯n. How is X¯ n distributed - name the distribution. Use an important theorem. Do it in R commander.
Create a column of numbers going from 0 to 30. in binomial distrubution with n=30 and p=0.5. Remember that the variance is the expected value of the squared deviations from the mean. In the next column, compute the product of the probability of each outcome and the squared deviation from the mean. Place the sum of the 31 values in the cell next to the cell in which you have computed the variance as a function of the parameters.

For a standardized psychology examination intended for psychology majors, the historical data show that scores have a mean of 515 and a standard deviation of 170. The grading process of this year's exam has just begun. The mean score of the 35 exams graded so far is 518. What is the probability that a sample of 35 exams will have a mean score of 518 or more if the exam scores follow the same distribution as in the past? Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.

Suppose you have the population 50 and 80 and that their corresponding z-scores are -1 and -2, respectively. Is it possible to determine the populations mean and standard deviation?
Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. This method is designed to increase the likelihood that each baby will be a girl, but assume that the method has no effect, so the probability of a girl is 0.5. Assume that the groups consist of 45 couples. Complete parts (a) through (c) below. a. Find the mean and the standard deviation for the numbers of girls in groups of 45 births. The value of the mean is μ=nothing. (Type an integer or a decimal. Do not round.) The value of the standard deviation is σ=nothing. (Round to one decimal place as needed.) b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high. Values of nothing girls or fewer are significantly low. (Round to one decimal place as needed.) Values of nothing girls or greater are significantly high. (Round to one decimal place as needed.) c. Is the result of 31 girls…

Suppose that the distribution of the grades of students in MAPEH performance 1 is roughly normally distributed with a mean of 85 and a standard deviation of 5 a. Between what values do we expect the grades of the middle 68% of the MAPEH students in performance 1 lie? b. Suppose you randomly select 16 MAPEH students, find the probability that the average grades of these students is at least 86. c. A MAPEH student whose grades lies in the upper 1% of the distribution (inclusive of the 1% cutoff) is considered extremely performing in Performance 1. Can you say that Jazzer, a randomly selected student who obtained a grade of 95, is one of those who performed extremely in Performance 1?

From a sample with n = 12, the mean number of televisions per household is 2 with a standard deviation of 1 television. Using Chebychev's Theorem, determine at least how many of the households have between 0 and 4 televisions. At least of the households have between 0 and 4 televisions. (Simplify your answer.)
