Explanation & Answer
p-value for z = -1.58 is 0.057053.....Simple you can use =normsdist(z) function in excel or solve using this formula
alpha = 0.06 and p-value = 0.057
p-value < alpha
Hence "we reject the null hypothesis"

CSU Week 3 Normal Distributions Questionnaire
Problems need to include all required steps and answer(s) for full credit. All answers need to be reduced to lowest terms where possible. If the answer is in %, show two decimal places.Answer the following problems showing your work and explaining (or analyzing) your results. Submit your work in a typed Microsoft Word document.The average score of a statistics class was 71 with a standard deviation of 8.What is the z score of a student with a grade of 68? (2.5 pts)What is the z score of a student with a grade of 80? (2.5 pts)Using the same data in #1 answer the following:Approximately 68% (one standard deviation) of the scores are between ________ and _________ (2.5 pts)Approximately 95% (two standard deviation) of the scores are between _________ and _________ (2.5 pts)Most values of the standard normal distribution are between __________. (3 pts)-3 and 30 and 10 and 31 and 3(a) If the standard deviation of a data set is 1.3, what is the variance? (2.5 pts)(b) If the variance is 36, what is the standard deviation? (2.5 pts)Let X have a normal distribution with mean µ= 20 and standard deviation σ = 4. Determine the area in the normal curve for which:P (X > 28) (2.5 pts)P (X > 12) (2.5 pts)P (X > 24) (2.5 pts)The IQ scores of students listed below are from a SAMPLE of MATH 300 class.

SWC Stats Alcoholic Beverages a Student Consumes Question
Use this activity to assess whether you and your peers can: Use StatCrunch to conduct a hypothesis test to test a claim about a population mean.State an appropriate conclusion in context.Explain the meaning of each relevant item from the StatCrunch output.ContextA group of 75 college students from a liberal arts college were randomly sampled and asked about the number of alcoholic drinks they have in a typical week. The file containing the data is linked below. The purpose of this study (Links to an external site.) was to compare the drinking habits of the students at the college to the drinking habits of college students in general. In particular, the dean of students, who initiated this study, would like to check whether the mean number of alcoholic drinks that students at his college have in a typical week differs from the mean of U.S. college students in general, which is estimated to be 4.73.VariablesThe number of alcoholic beverages a student consumes in a week.DataOpen the drinks datafile in the Stats at Cuyamaca College group on StatCrunch (directions - opens in a new tab).Note - the drinks datafile is different from the college_drinking file.PromptThe drinks datafile is available in the Data section above.Let 𝜇μ be the mean number of alcoholic beverages that students in the liberal arts college drink in a typical week. State the hypotheses. Here is a histogram of the data. Can we safely use the t-test with this data? Explain. Perform the t-test using StatCrunch. (directions) Copy and paste the information from the StatCrunch output window into the textbox.Based on the P-value, state your conclusions in context. Use a 5% level of significance. NOTE: You do not need to double the P-value for this two-tailed test. StatCrunch calculates the P-value for you.Using the context of this scenario, explain the meaning of each of following items from the StatCrunch output for the hypothesis test.Std.

Qualitative Research
For this assignment, you will explore the foundations and history of qualitative research methods.You also will consider the unique characteristics that distinguish qualitative research from other forms of inquiry.To prepare for this Assignment:Consider the statement: Qualitative researchers study people in their natural settings, attempting to make sense of phenomena in terms of the meanings people bring to them.Expand on this simple statement. In 4–5 paragraphs.Explain several dimensions of this paradigm that make qualitative research interesting and unique.Be sure to use the terminology you are learning (including but not limited to “phenomena”, “constructivist,” and “naturalistic”), and provide historical context.
