what would be the null hypothesis for the permutation test? ### Comparing Word Puzzle Completion Times#### Research OverviewA researcher aimed to compare the times required to complete a word puzzle based on participants' levels of experience with video games. The study categorized participants into two groups: those with minimal experience and those with substantial experience. Participants were randomly selected for the experiment.#### DataThe time taken (in minutes) by participants from each group to complete the puzzle is presented in the table below:| Minimal Experience | Substantial Experience ||--------------------|------------------------|| 17 | 12 || 18 | 13 || 17 | 14 || 19 | 15 || 17 | 18 || 16 | 100 || 14 | 17 || 14 | 14 |#### Null HypothesisThe null hypothesis for this two-sample t-test would be:- \( H_0: \mu_d = 0 \) (No difference in the population means of the two groups)##### Other Hypotheses Options:- \( H_0: p_1 - p_2 = 0 \)- \( H_0: \) Identical Population Distributions- \( H_0: \) Identical Sample Distributions### Graph ExplanationIf there were any graphs or diagrams present, they would typically show a visual comparison of the completion times between the two groups, possibly including:- **Box Plots:** To display the distribution of completion times within each experience level.- **Histograms:** To show the frequency of completion times across different intervals for each group.- **Scatter Plots:** To visualize any potential correlation between experience level and completion time.By comparing the provided data and visual aids, researchers can observe trends and differences in performance between the two categories of participants, ultimately testing the null hypothesis to determine if video game experience significantly affects puzzle completion time.

The permutation test is a nonparametric test.

Suppose that a statistics teacher asks his students to each randomly pick one of the numbers 0, 3, 5, 7. His general theory is that the proportion who pick the number 0 will be less than what would be expected from random selection. Use p to represent the population proportion that would pick the number 0. (a) What is the specific value of p that corresponds to true random selection? p = (b) In terms of p, write null and alternative hypotheses for this situation. Ho Ha: P <
A student performs a test of Ho: u = 100 versus H,: > 100 and gets a P-value of 0.044. The student says, "There is a 0.044 probability of getting the sample result I did by chance alone." What did the student do wrong in their explanation? The student forgot to include the condition and the direction in their interpretation. The student forgot to state the conditional probability. The student forgot to make a decision about the null hypothesis. The student forgot to include a directional range of values. O The student did nothing wrong. The interpretation is fine.
