### Reaction Time Experiment AnalysisIn this experiment, a participant is exposed to a constant soft noise that is occasionally interrupted by a slightly louder sound at unpredictable intervals. The participant's reaction times to these louder sounds are recorded. Below is the list of reaction times (in milliseconds) for 7 trials:**Reaction Times (ms):** 541, 800, 667, 362, 542, 667, 800**Questions:**#### (a) What is the median of this data set? If your answer is not an integer, round your answer to one decimal place. **Median:** [____]#### (b) What is the mean of this data set? If your answer is not an integer, round your answer to one decimal place. **Mean:** [____]#### (c) How many modes does the data set have, and what are their values? Indicate the number of modes by clicking in the appropriate circle, and then indicate the value(s) of the mode(s), if applicable. **Modes:** - Zero modes [ ] - One mode: [____] - Two modes: [____] and [____]**Instructions:**To calculate these statistics, you may use any standard statistical methods or tools. You can also send the data to a calculator for easier computation by clicking the "Send data to calculator" button. ### Explanation of Key Statistical Terms- **Median:** The median is the middle number in a sorted list of numbers. To find the median, arrange all numbers from smallest to largest and identify the middle number.- **Mean:** The mean or average is the sum of all numbers divided by the count of numbers.- **Mode:** The mode is the number that appears most frequently in a data set. A data set can have zero, one, or multiple modes.### Example ExplanationConsider the sorted version of the reaction times data: 362, 541, 542, 667, 667, 800, 800.1. **Median Calculation:** - Sorted data: 362, 541, 542

Ti A fitness instructor at a large gym would like to know if the individuals that take fitness classes in the morning tend to get in a greater number of steps than individuals that take evening fitness classes. She selects a random sample of 10 individuals that take fitness classes in the morning and 10 individuals that take fitness classes in the evening. She gives each person a step-counting At 10 device to wear for one week. At the end of the week she collects the devices and calculates the mean and standard deviation of the number of steps taken by the individuals in each group. Let uM = the true mean number of steps taken by all individuals who take fitness classes in the morning and HE = the true mean number of steps taken by all individuals who take fitness classes in the evening. What are the appropriate hypotheses for this test? O Ho: HM - HE = 0; Ho: HM - HE 0; H: HM - HE = 0 O Ho: HM HE = 0; Ha: HM - HE > 0 O Ho: HM HE < 0; H HM - HE = 0 O Ho: HM - HE - 0: H HM - HE #0
