The image presents a small data table followed by a question about hypothesis testing. **Data Table:**- The table lists names alongside two numbers each, potentially representing scores or measurements. - Bubba: 61, 79 - Amber: 72, 86**Question:**- "Which hypothesis test needs to be employed here?"**Answer Choices:**- ○ z test- ○ one-sample t test- ○ dependent t test- ○ independent t test- ○ Pearson’s rThere are no graphs or diagrams in this image. The context suggests a requirement to determine an appropriate statistical test for the data displayed. **Title: Exploring the Relationship Between Age and Golf Performance**A researcher is investigating the connection between a golfer's age and their performance on the course. The claim is that golf performance tends to improve with age—meaning, as a person grows older, their golf scores decrease (where a lower score indicates better performance). To explore this hypothesis, the researcher randomly selected eight golfers from a local golf course to record their ages and most recent golf scores. The collected data is organized below:| Golfer’s Name | Age (years) | Golf Score ||---------------|-------------|------------|| Diego | 23 | 92 || Tiger | 14 | 112 || Bogart | 38 | 77 || Marilyn | 43 | 84 || Jennifer | 49 | 81 || Mitch | 36 | 72 || Bubba | 61 | 79 || Amber | 72 | 86 |**Data Explanation:**- **Age (Variable 1):** Represents the golfer's age in years.- **Golf Score (Variable 2):** Indicates the golfer's most recent score. In golf, lower scores signify better performance.**Discussion:**The goal is to determine if there is a statistically significant relationship between age and golf performance using hypothesis testing. The appropriate test to employ here needs to be considered—options include a z-test or another relevant statistical method.**Hypothesis Test:**- Which hypothesis test should be employed? - o z testThe table and information provided will aid in analyzing whether older age correlates with better golf performance, as suggested by lower scores.**Note for Learners:**Understanding the proper application of statistical tests in relation to the data can illuminate trends and relationships. It's important to choose a test suitable for the data's characteristics and the research question at hand.

It is given that the data of the relationship between age and golf performance.

Research Question: Is there a difference between the average height of male and female basketball players in the club? 28 male and 25 female basketball players from the club were randomly selected. Use the following image to answer the questions below. Carry out an appropriate hypothesis test to answer the above Research Question. Q1) The null and alternative hypotheses are : Choose one from below -H0: μ = 0, H1: μ ≠ 0 -H0: μ = 170, H1: μ ≠ 170 -H0: μm- μf = 167.489, H1: μm- μf ≠ 167.489 -H0: μm- μf = 0, H1: μm- μf ≠ 0 H0: μm- μf = 170.27, H1: μm- μf ≠ 170.27 Q2) What is the assumption you need to make ? Choose one from below -The shape of the histogram indicates that the scores may be from a normal distribution and/or the sample size is reasonably large so the sample mean will be from a normal population -None of these -Since nπnπ and n(1−π)n(1−π) are both ≥5, the Central Limit Theorem applies and we can assume that p arises from a normal distribution -The boxplots…
