So,the percentage of baskets that Charlie make is 65%
In this case, since the standard deviation is known and
the sample size is less than 30, we will use the t-distribution. The formula
for calculating the confidence interval is:
Confidence Interval = X ± t * s / sqrt(n)
Where,
X = sample mean = $664.14
t = t score (taken from standard distribution tables)
s = standard deviation = $297.29
n = sample size = 14
At Degrees of Freedom = n – 1 = 13 and 98% Confidence
interval, z = 2.65
Substituting the values in the equation:
Confidence Interval = 664.14 ± 2.65 * 297.29 / sqrt(14)
Confidence Interval = 664.14 ± 210.55
Confidence Interval = 453.59 to 874.69

Answer:
Attribute
Step-by-step explanation:
Attribute is defined as the characteristic or quality of an object. When we qualify statistical data based on attributes, it is referred to as qualitative classification of data.
Example of attributes are religion, educational level, gender, color of hair,etc. A change in attribute can only be expressed qualitatively.
The vertex is at (0,-5), therefore the range goes from (-infinity, - 5]
