Right off the bat I could see a strong positive linear trend. Proving my hypothesis that an individual a taller individual has a larger shoe size. I came to this conclusion by plugging my data into a scatter plot. Where height in inches was represented on the x-axis‚ and shoe size was on the y-axis. Chart 1 below displays the

regression is to determine if there is a correlation between the poverty rates and literacy rates in different states within USA. My null and alternate hypothesis are as follows: Null hypothesis: Ho: β1 = 0 This hypothesis states that there is no correlation between the literacy and poverty rates Alternate hypothesis: Ha: β1≠0 This is the hypothesis we want to prove‚ there is correlation between the literacy rate and poverty rates The first step I did was to create a scatter plot for the data and

The significance level is α 0.05= -1.645. According to Course Project data‚ when I generate the data of income in Minitab‚ I found the standard deviation‚ which is 14.64. Then next step is calculating the z-value by Minitab‚ which is -3.02. Consequently; z-value < α 0.05 -3.020.4 The hypothesis test claims that

the observations taken from each of the populations are normally distributed‚ the Friedman test is used when no distrubutional assumptions are necessary. The following are the steps in doing the Friedman Test: a. State the null hypothesis. b. State the alternative hypothesis. c. Let t represent the treatment and b represent the blocks. Arrange the recorded observation for each treatment-block combination in a two-way table in which the treatments are placed in columns and the blocks in rows.

the two groups. The null hypothesis should be rejected because the P-Value is 0.005 which would mean that the groups are different. 2. State the null hypothesis for the Baird and Sands (2004) study that focuses on the effect of the GI with PMR treatment on patients’ mobility level. Should the null hypothesis be rejected for the difference between the two groups in change in mobility scores over 12 weeks? Provide a rationale for your answer.

Develop a Research Question to Compare a Single Sample Mean to a Known or Hypothesized Population Mean: In your area of psychology‚ formulate a research question that can be addressed using a one sample t-test.

From this case‚ there are two types of errors‚ which the consortium can make. A Type I Error is referred to as a “false positive.” A Type I error would be made when the null hypothesis is rejected when it should be accepted. This error may occur if the consortium defends any lawsuit against them if they are using 6% (6/100) as their surveying result. The results of the sample size of 100 people indicate that the percentage range is from 1.35% to 10.65%. The test results can be higher than 10%‚ but
