For a hypothesis test of a single population proportion, we can use the "Statistics" tab in the Probability Calculator in Geogebra or "Stat > BasicStatistics > 1 Proportion" in Minitab.For Geogebra, click the drop-down menu near the top (default is "Z Test of a Mean") and choose "Z Test of a Proportion." Enter the number ofSuccesses (usually written as I, which is not the same thing as I), and sample size N. We'll use a sample of size 16 in which there are 5successes.For Minitab, first select "Summarized Data" from the drop-down menu, then enter the number of events (Successes, x), and numer of trials(sample size N). Check "Perform Hypothesis Test" and enter the hypothesized proportion. Click Options and select your alternate hypothesis and"Normal Approximation" from the drop-down list.For a hypothesis test of Ho :p= 0.5 versus HA : p<0.5:• The given sample has a test statistic of• The P-value for the test isFor a hypothesis test of Ho :p= 0.3 versus HA: p > 0.3.The given sample has a test statistic ofThe P-value for the test isFor a hypothesis test of Ho p = 0.3 versus HA: p 0.3:• The given sample has a test statistic of• The P-value for the test is

Please also explain why you determined whether or not the results are statistically significant. The mean score on a psychological characteristic for women is 25 (SD = 5) and the mean score for men is 24 (SD = 5). There were 12 women and 10 men in this study.
What is the name of the test used?
Out of 57 high school female athletes, data was collected on how much they were able to bench press. From this data we get x=79.9,Q1=70, Q2=80, and Q3=90. Determine if the data distribution is skewed or symmetric. Give 2 reasons to back up your answer.

A stratified sample is sometimes recommended when?
On average, a sample of n = 36 scores will provide a better estimate of the population mean than a sample of n = 49 scores from the same population.
The accompanying data set includes volumes (ounces) of a sample of cans of regular Coke. The summary statistics are n = 36, x = 12.199 oz, s = 0.100 oz. Assume that a simple random sample has been selected. Use a 0.01 significance level to test the claim that cans of Coke have a mean volume of 12.00 ounces. Does it appear that consumers are being cheated? Click the icon to view the data set of regular Coke can volumes. Identify the null and alternative hypotheses. Ho: H₁: (Type integers or decimals. Do not round.) Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Decide whether it appears that consumers are being cheated. the null hypothesis. There because consumers are getting sufficient evidence at the 0.01 significance level to 12.00 ounces. the claim that cans of Coke have a mean…
When comparing test scores of two groups, a difference of one point would never be highly statistically significant, even if you had a really large sample. True False
There are many ways to measure the reading ability of children. One frequently used test is the DRP or Degree of Reading Power. The national average score in DRP test is 32. We want to determine if there is sufficient evidence at the 5% level to suggest that the mean score of all third graders in YOUR district is higher than the national mean. The DRP scores for a simple random sample of 41 third graders in that suburban school in YOUR district yielded a mean of 35.2. Assume that the population of DRP scores of third graders in that suburban school district are normally distributed with a population std.dev of 11.
A community college professor is interested in determining the relationship between the number of posts students make on Schoology and their respective grades. He planned to correlate the results from a sample from all his classes, however, due to time constraints, he decided to sample only from students with high grades. As his statistical consultant, state whether or not you support his plans and why.
