There seems to be no end to how large the signing bonuses professional athletes can obtain when they start their careers (Peyton

Manning - $11.6 million). Suppose a sample of 18 new NFL players report their signing bonuses at the start of the 1998 season, and the results show a mean of $3.81 million and a standard deviation of $1.7 million. Estimate with 90% confidence the mean signing bonus for that season (in millions).

Anestetic [448]3 years ago
6 0

Answer:

3.113, 4.507

Step-by-step explanation:

From the given values:

Mean = 3.81

Standard deviation = 1.74

Therefore

M = √(1.72/18) = 0.4

μ = M ± t(sM)

μ = 3.81 ± 1.74*0.4

μ = 3.81 ± 0.697

Recall that the mean is estimated at 90% confidence level,

Hence,

= 90% CI [3.113, 4.507]

vodomira [7]

Answer:

5/ 19 ≈ 0.26 = 26%

Step-by-step explanation:

given: student is female. there is a 100% chance that the student is female

probability we want = (favorable outcomes) / (total outcomes)

total outcomes = 19 because there are 19 female students and the student must be female

favorable outcomes = 19 - 14 = 5 females who do not have an A in the class

probability = 5/ 19 ≈ 0.26 = 26%

The graph shows the relationship between time
musickatia [10]

Answer:

The machine can make 24 bottles of soda per minute

Step-by-step explanation:

Looking at the graph of the relationship, we can see that the number of bottles per minute simply represent the slope of the line

Thus, by calculating the slope using the given points, we can have the number of bottles per minute

We have the formula as;

m = (y2-y1)/(x2-x1)

(x1,y1) = (4,96)

(x2,y2) = (6,144)

m = (144-96)/(6-4) = 48/2 = 24
