Answer: Are you sure you wrote out the formula correct? if so, then based of the formula, the answer is -1487. Since the question asks to use the formula, we end up with this answer. I am pretty sure your missing a variable or have missed typed the formula because a negative height isn't possible unless the force that was pushing the ball down was great enough that the second the ball flew up, it went flying down at incredible speed. One example of this is if you through a ball of a mountain up in the air, but the wind direction was going down. This would result in the ball going up for only measly second, then instantly dropping down on rapid speeds.
Explanation: Since we are already given all necessary values in the story problem, all that is left is to substitute into the formula and solve algebraically.
Step 1.) Gather what you know
(+) Formula for height; h=5+60t-1612
(+) We know we need to find the ball's height after 2 second's in air.
(+) h=height
(+) t = time
Step 2.) Understand what you need to do. Since the formula determines the height of the kicked object given the value of t (time), we need to substitute t with the value necessary to know how high the object will fly in that given time. In this story problem, it is asking us the ball's height in 2 seconds.
Notice: The object height is calculated by the speed of the object in the air + other variable which include the initial height of the object and more.
Step 3.) Use the formula and substitute. Since we know how the formula works, we know that if we substitue any t (time) in the formula, then it will give use the height based of the t (time) we have given.
1.) h = 5 + 60(t) - 1612
2.) h = 5 + 60(2) - 1612
Step 4.) Use Algebra to solve the equation.
1.) h = 5 + 60(2) - 1612
h = 5 + 120 - 1612
h = 125 - 1612
h = -1487
It will be the third choice -5, -3, 1, 4 hope this helps good luck
Answer:
The marketing department committed a Type I error because the marketing department rejected the null hypothesis when it was true. The probability of making a Type I error is 0.01.
Explanation:
Null Hypothesis: H₀ : µ = 58.58
Alternative Hypothesis: H₁ : µ> 58.58
A type I error is made by the marketing department if the null hypothesis is rejected when it is true and a type II error occurs, when the marketing department fails to reject the null hypothesis when it should be rejected.
The probability of making a Type I error is α, which is the level of significance you set for your hypothesis test, in our case 0.01 while the probability of making a Type II error is β, which depends on the power of the test.
Based on this we can therefore conclude that the marketing department committed a Type I error because the marketing department rejected the null hypothesis when it was true. The probability of making a Type I error is 0.01.
