---### Evaluating the Influence of a Treatment using Normally Distributed Populations**Context**A researcher is evaluating the influence of a treatment using a sample selected from a normally distributed population with:- Mean (μ) = 50- Standard Deviation (σ) = 10The researcher expects a +5-point treatment effect and plans to use a two-tailed hypothesis test with a significance level (α) of 0.05.**Graph Explanation**The image includes a Standard Normal Distribution graph, showcasing a bell curve centered at a mean of 0.0 with a standard deviation of 1.0. The distribution is divided into two halves at the mean:- The left side of the curve (shaded in blue) represents the lower half, with an area of 0.5000.- The right side of the curve (shaded in brown) represents the upper half, also with an area of 0.5000.**Steps to Compute the Power of the Test:**1. **Computing the power of the test for n = 4 individuals:** - The power for the test is the probability of obtaining a z-score [greater/less] than [z-value], which corresponds to p = [p-value]. - Thus, the power of the test is [percentage]%.2. **Computing the power of the test for n = 25 individuals:** - The power for the test is the probability of obtaining a z-score [greater/less] than [z-value], which corresponds to p = [p-value]. - Thus, the power of the test is [percentage]%.**Interactive Component**Students can dynamically control the z-value and see corresponding changes in p-value, enhancing their understanding of statistical power within hypothesis testing.---**Note:** Be sure to include actual z-values and p-values based on the specific analysis and computations performed.

Compute the power of the test if the researcher uses a sample of n = 4 individuals. The power for the test is the probability of obtaining a z-score than , which corresponds to p = Thus, the power of the test is %. Compute the power of the test if the researcher uses a sample of n = 25 individuals. The power for the test is the probability of obtaining a z-score than which corresponds to p = Thus, the %3D power of the test is 이0.

We want to test whether or not more students are absent on Friday afternoon classes than on Wednesday afternoon classes. In a random sample of 300 students with Friday afternoon classes, 62 missed the class. In a different random sample of 300 students with Wednesday afternoon classes, 22 missed the class. The table below summarizes this information. The standard error (SE) is given to save calculation time if you are not using software. Class Day total # of absences (x) total # of students (n) Friday Wednesday (b) Find the critical value. (c) Find the p-value.

Previously, 4% of mothers smoked more than 21 cigarettes during their pregnancy. An obstetrician believes that the percentage of mothers who smoke 21 cigarettes or more is less than 4% today. She randomly selects 115 pregnant mothers and finds that 3 of them smoked 21 or more cigarettes during pregnancy. Test the researcher's statement at the α=0.1 level of significance. find p value

Students in an elementary school both boys and girls were asked if they are willing to write a letter to their mother on Mother's Day as an assignment. Out of the 30 boys, only 9 answered "yes" while out of the 45 girls, 39 said that they are willing to write to their mother on Mother's Day. At 99% level of confidence, is there enough evidence to say that the proportion who said "yes" is more for girls than boys? .

Suppose you are conducting a test of significance to try to determine whether your cat, Hope, will go to the correct object (out of two) when it is pointed to. You test Hope 100 times and finds she goes to the correct object in 70 out of those 100 trials. In this scenario, what is the variable? Whether or not Hope goes to the correct object The 100 trials The proportion of the 100 trials that Hope goes to the correct object The long term proportion (probability) that Hope will go to the correct object
Question(14): A researcher wanted to know whether children who live in two different neighbourhood (Willowdale and Forresthill) got different amount of excerise. Children were randomly selected from the two neighbourhoods (40 in each). and filled out the daily activity report to measure their excerise. The number of minutes of excerise were tallied and recorded. The The researcher then conducted an independent sample t test using MS-EXCELL. The result are shown in the image below. Inspect the MS- EXCELL output.Did the researcher conduct their t test assuming equal variance.? Write out Step 5 by including both the formal answer and the conclusion. The five steps are: Step 1:State the hypotheses and identify the claim. Step 2: Compute the test value Step 3: Compute the critical value. Step 4:Make the decision (reject or not reject) Step 5:Summaize the results. Note: you only need to submit step 5, and round snswer to decimal places MS-EXCELL output:…
Victims of Violence A random survey of 86 women who were victims of violence found that 20 were attacked by relatives. A random survey of 54 men found that 6 were attacked by relatives. At α=0.10, can it be shown that the percentage of women who were attacked by relatives is different from the percentage of men who were attacked by relatives? Use p1 for the proportion of women who were attacked by relatives. Use the P-value method with tables. State the hypotheses and identify the claim with the correct hypothesis. H0: claim/do not claim? H1: claim/do not claim? This hypothesis test is one tailed/two tailed? Compute the test value. Round all intermediate steps to four decimal places and always round z score values to tow decimal places. Z= Compute the P-value. Round the answer to four decimal places. P -value = Make the decision. Reject/do not reject the null hypothesis. Summarize the results. There is/ is not enough evidence to support the claim t
