Leah manages an ice cream store. She wants to see if there is a relationship between the number of ounces of ice cream for each size and  the number of ice creams sold. For one month Leah counted the number of each size of ice cream sold and put her data in the chart below.Size of Ice Cream Ounces of Ice Cream Number Sold in One MonthKid's Size 2 11Small 4 29Medium 6 52Large 8 45Super Size 12 12 Leah created the scatterplot below.Which of the following interpretations does this scatterplot best support?Group of answer choicesThe negative quadratic trendline is the best choice for this data because it looks like the medium size was the most frequently purchased (the vertex) and both the kid's size and the super size were purchased less frequently.The positive quadratic trendline is the best choice for this data because it looks like the medium size was the most frequently purchased (the vertex) and both the kid's size and the super size were purchased less frequently.The decreasing exponential trendline is the best choice for this data because purchases decreased exponentially as the ounces increasedThere is no relationship between the ounces of ice cream and the number sold.A linear trendline with a positive slope is the best choice for this data because it is the simplest model and because customers purchased more ice creams as the number of ounces increased.

What is the purpose of using a scatter plot?Review LaterTo show the distribution of a single variableTo compare the distribution of two variablesTo show the relationship between two variablesTo show the ranking of categories

The scatter plot shows the number of hours worked and money spent on entertainment by each of 21 students. Also shown is the line of best fit for the data.Fill in the blanks below.y510152025303540455055606570x2468101214161820220AmountofmoneyspentonentertainmentindollarsNumberofhoursworked(a)For these 21 students, as the number of hours increases, the amount of money spent tends to ▼(Choose one)(b)For these 21 students, there is ▼(Choose one) correlation between the number of hours worked and the amount of money spent.(c)Using the line of best fit, we would predict that a student working 12 hours would spend approximately ▼(Choose one)

Caroline asked several people about their age and how much television they watch each night. She recorded the data in a scatterplot.What can be concluded from the scatter plot?

How does a scatter diagram help in identifying the type of relationship between two variables? By showing the direction of the relationship By calculating the coefficient of correlation By ranking the data points By showing the frequency distribution

Jacob wants to see if there is a relationship between the speed of a male runner and his age. He collected the age and race time from 27 male runners in a local 200 meter race. His data is depicted in the scatterplot below.Which of the following interpretations does this scatterplot best support?Group of answer choicesThe decreasing exponential trendline is the best choice for this data because older men's running times are exponentially shorter than younger men's times.There is no relationship between men's ages and their running times in the 200 meter race.A linear trendline with a negative slope is the best choice for this data because older men's running times are shorter than younger men's times.The quadratic trendline is the best choice for this data because from Jacob's scatterplot it looks like men around 40 have the slowest running time (the vertex). Men both younger and older than 40 are faster than 40 year olds.A linear trendline with a positive slope is the best choice for this data because older men's running times are longer than younger men's times.
