Answer choices:
1. The potato was launched from the ground.
-
False. 20 feet above the ground
2. The flight is symmetric about the line t = 2.
-
False. Line of symmetry is t=3
3. The potato reaches a maximum height of about 3 ft
-
False. Maximum height is about 150 ft
4. The potato is in the air during the interval 0
- Unclear. no interval given
5. The potato reaches its maximum height after about 3 seconds in flight.
6. h(2)=h(5)
- False. h(2) = 140 ft, h(5) = 80 ft
Answer:
A) Null Hypothesis;H0: μ = 5
Alternative Hypothesis;Ha: μ ≠ 5
B) test statistic = -2.1226
C) p-value = 0.0598
D) Option A is correct
Step-by-step explanation:
We are given;
x = 4.52 minutes
s = 0.75 minutes
μ = 5 minutes
n = 11
degree of freedom = n - 1 = 11 - 1 = 10
A) The hypotheses are;
Null Hypothesis;H0: μ = 5
Alternative Hypothesis;Ha: μ ≠ 5
B) t-statistic = (x - μ)/(s/√n)
(4.52 - 5)/(0.75/√11) = -2.1226
C) From the t-score calculator results attached, the p-value is approximately 0.0598.
D) The P-value of 0.0598 is is greater than the significance level of 0.01, thus we fail to reject the null hypothesis, and we say that the result is statistically nonsignificant. So option A is correct.
