Question one It has been noted that the amount of time people spend shopping in supermarkets has decreased due to the global pandemic. Based on this realization, the manager of Power Supermarket decided to collect data for the length of time people spend in his supermarket during a one week period. He is aiming to use the data to help him decide if the supermarket should be converted to a virtual supermarket/a delivery based one. a. Use the information below to construct two frequency polygons. b. Do you think that Power Supermarket should close their doors? Explain your answer. *Assume that a person who spends more time in a supermarket buys a lot of goods and a person who spends a short time in a supermarket, buys few goods.

Section H: Hyla chrysoscelis is a type of gray tree frog with a distinct mating call. Frogs are cold-blooded animals, and their physiology is affected by variations in temperature. Researchers wanted to know if the mating song of Hyla chrysoscelis is affected by the temperature of its natural habitat. They observed the mating song frequency (y in notes/sec) and the habitat (x in °Celsius) of 20 Hyla chrysoscelis in the wild. We aim to express the relationship between and y by using the simple linear regression model Yį = ßo + ß₁ x; + Eį.

Use the data given in the three scenarios below to produce scatter plots, determine the type of model demonstrated in each example and then answer the questions based on the graph you created. Scenario 1 Rescue 911 In a rural community, fire and paramedic crews must service a large region. They often cover 2 or 3 towns several kilometres apart. These crews travel, on average, 70 km/h to their destination. The Chief of Station 42 wants to determine the time required to reach the patient's home (response time) for his region. The station is located next to the local hospital. The Chief knows the distances to each community that he services, including Deerborn, the furthest community, at 55 km away. Using the data below, create a scatter plot showing the relationship between distance to patient and response time. Distance to Patient (km) Response Time (minutes) 10 8.6 15 12.9 40 34.3 50 42.9 55 47.1
