True or False: A race car driver tested his car for time from 0 to 60 mph, and for 20 tests obtained a mean of 4.85 seconds with

sattari [20]

Answer:

The given statement is false.

Step-by-step explanation:

We are given the following in the question:

95% confidence interval: (4.53,5.18)

Sample mean, $\bar{x}$ = 4.85 seconds

Sample size, n = 20

Alpha, α = 0.05

Sample standard deviation, σ = 1.47 seconds

Degree of freedom = n - 1 = 19

95% Confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 4 and}~\alpha_{0.01} = \pm 2.09$

$4.85 \pm 2.09(\dfrac{ 1.47}{\sqrt{20}} )\\\\ = 4.85 \pm 0.69 \\\\= (4.16 ,5.54)$

Thus, the calculated confidence interval is different from the given confidence interval.

Hence, the given statement is false.

If two sides of a triangle are 3 cm and 5 cm in length, which could NOT be the measure of the third side? A) 2 cm B) 3 cm C) 4 c

enot [183]

In geometry, there is a theorem that states: The sum of any two sides of a triangle is greater than that of the third

Let's try to plug in and find if any two sides added together will be greater than the third:

a) 2 cm

3+5=8 and 8>2 [acceptable]

2+3=5 but 5=5 [not acceptable]

2+8=10 and 10>5 [acceptable]

b) 3 cm

3+3=6, 6>5 [good]

3+5=8, 8>3 [good]

.....

etc

We found that the answer has to be 2cm, because if we were to add a side of 2cm with 3cm, it would equal to the third side and the theorem states that the sum has to be greater

Hope this helped :) If so, leave a rating :)
