Answer:
Step-by-step explanation:
Before answering we must clearly understand the difference between a statistic and a parameter.
The characteristic of a population is parameter. Example, population mean, population std deviation, population variances are called parameters.
Sample mean, sample std dev, sample variances are called statistics.
Here given that 7 math classes were surveyed and average was calcualted as 83%
Hence only sample mean = 83% and this is hence a statistic
If all 15 math classes surveyed and average taken that would have been the parameter.
Answer:
$0.75
Step-by-step explanation:
We have been given that a proportional relationship between the number of pounds of carrots (x) and the price in dollars (y).
We can represent this information as: .
We are also told that the ordered pair (8, 6) is on the graphed line. Let us substitute x= 8 and y= 6 in our proportional equation to find the constant of proportionality.
Now let us substitute k=3/4 and x=1 in our proportionality equation.
Therefore, the price of 1 pound of carrots will be $0.75.
The probability that he will guess correctly is:
1/5
