An observational study is a study that has to do with the observation of individuals involved in the study. In such a study, zero effort is put to change the outcome.
This question tells us that the random sample of 291 individuals that underwent the weight loss program would go through a system of follow up to find out the change in weight. Therefore the design of the study is clearly an observational study.
The graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.
Step-by-step explanation:
The difference between continuous and discrete graphs and functions is that a discrete function allows the variables to be only certain points in the interval, usually only integers; meanwhile, a continuous function allows the variables to be any points in the interval. Here, both variables are discrete, that is, the number of people is {0, 1, 2, 3, ...}, and days are {Monday, Tuesday, Wednesday, ...}
B because C has nothing to do with the story and A is not a very logical answer D is a very close answer but if he would listen to his friend he wouldn’t have overworked himself

d. How many people sign up for lessons after seeing the ad
Explanation:
Conversion tracking is a free resource that indicates what occurs once a customer has interacted with your ads (if he/she bought one of your items, subscribed to your newsletter, got in touch with your business, or installed your app in his phone). After a customer has fulfilled an action you point as valuable, this action becomes known as conversion.
A. 1.20x; individuals signing up the day of the activity get charged 20% more
Step-by-step explanation:
Amount charged before the day of activity = x
Amount charged on any individual who decides to sign up on the day of activity would be the normal price, x dollars, plus an additional price of 0.20x dollars.
0.20x = 20% of x.
That is, the additional fee added to the normal price is 20% of the normal price.
Therefore, amount paid on the day of the activity is x + 0.20x = 1.20x dollars.
What this fee means is that those who decide to sign up on the day of the activity are charged 20% more.
