Astore asked 250 of its customers how much they spend on groceries each week. the responses were also classified according to the gender of the customers. we want to study whether there is a relationship between amount spent on groceries and gender. a meaningful display of the data from this study would be:
(a) side-by-side boxplots(b) a pie chart(c) a histogram(d) a scatterplot(e) a two-way table

D) a scatterplot

Step-by-step explanation:

Given that a store asked 250 of its customers how much they spend on groceries each week. The responses were also classified according to the gender of the customers. We want to study whether there is a relationship between amount spent on groceries and gender

Since we are interested in the relationship or in statistical terms the correlation between two variables the best graph would be a scatterplot

Scatterplot is the graph in which independent variable on x axis and dependent variable on y axis and observed values are plotted.  This shows the trend of the relation whether linear, positive, strong etc.

Hence D) a scatterplot

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
