We surveyed 19 households in a neighborhood and asked the number of pets in each household. The data is as follows: 0, 0, 1, 1, 1, 2, 2, 2, 2, 2, 2, 3, 3, 4, 4, 5, 5, 6, 7 (a) Fill in the frequency table below. Keep answers as a fraction as needed. Data Frequency Relative Frequency 0 1 2 3 4 5 6 7 (b) What is my sample mean rounded to 2 decimals? You may use your calculator. State the calculator buttons used. (c) What is my sample standard deviation rounded to 2 decimals? You may use your calculator. State the calculator buttons used. (d) Construct a max/ min box plot on your scratch paper.

ScLi15- Determine whether results оf а reseаrch study аnswer the research questiоn The Biоdiversity-stability hypothesis suggests that more plant species in an area can enhance the stability and resilience of ecological communities (groups of other species), resulting in diverse communities being better able to withstand disturbances or environmental fluctuations. A study wanted to determine if the hypothesis applied to grassland areas. They manipulated the plant richness (number of plant species) by adding or removing plant species. Which statements best conclude the response of the community to these changes?
ScLi11- Identify predictiоns оf reseаrch pаpers A study wаnts tо test the following hypothesis: Precipitation patterns affect the flowering timing of plants. Researchers will test this hypothesis by performing field experiments setting up controlled plots of mango trees with varying levels of water availability to simulate different precipitation patterns. They will monitor these plots over one year and will monitor daily the appearance of flowering buds. provide direct observations of changes in flowering times. Which of the following would be appropriate predictions?
