Answer:
Neither the normal distribution nor the t distribution applies.
Step-by-step explanation:
Hello!
The histogram attached shows the salary (in dollars) of 63 football players.
As you can see most of the values of this distribution are around 0 and the distribution is extremely asymmetrical (right skewed).
To apply a t-test to study the population average the population has to have a normal distribution.
The same goes for the standard normal distribution, but in this case, considering that the sample is large enough (n≥30) you can apply the Central Limit Theorem and approximate the distribution of the sample mean to normal X[bar]≈N(μ;δ²/n), but since the population variance is unknown, this is also not applicable.
The correct choice is the last one, since the conditions to apply the t test and the standard normal are not met.
I hope this helps!
Answer:
$651.50
Step-by-step explanation:
Anything OVER 650 is paid in commissions.
Since total sales was 1880, the amount paid in commissions is:
1880 - 650 = $1230
Arlen will get 5% of 1230, that is:
5/100 = 0.05
0.05 * 1230 = $61.5
Weekly Pay = 590
Commissions = 61.5
Total Pay = 590 + 61.5 = $651.50
Last option is right.
I would say your answer would be 1.125 because the radius is half of the diameter so 2.25 / 2 gives you 1.125.
Step-by-step explanation:
he will be 17. he is going to grow 1.5 inch per year, if we do 1.8×8= 12.0 or 1 ft so it will take him 8 years to be 6feet
Answer:
13 units
Step-by-step explanation:
Giveb that :
Perimeter = 5/2 + 8/2 + 5/2 + 8/2
Hence, sum of the perimeter will be ;
The L. C. M of the denominator = 2
(5 + 8 + 5 + 8) / 2
= 26 / 2
= 13 units
Hence, the perimeter of the rectangle is 13 units
