QUESTION 1 Provide an appropriate response. Compute the standardized test statistic, X 2 , to test the claim σ 2 ≥ 12.6 if n = 1

Anna [14]

Answer: 11.667

Step-by-step explanation:

The formula to find the test statistic for chi-square test is given by :-

$\chi^2=\dfrac{(n-1)\cdot s^2}{\sigma^2}$

Given : Claim : $\sigma^2=12.6$

$n = 15\ ;\ s^2 = 10.5$

Then , the standardized test statistic will be :-

$\chi^2=\dfrac{(15-1)\cdot 10.5}{12.6}\\\\=\dfrac{14\cdot 10.5}{12.6}=11.6666666667\approx11.667$

Hence, the standardized test statistic $\chi^2=11.667$

If cos(θ)= -2/3 and θ lies in quadrant II, find the value of cotθ

Lera25 [3.4K]

$\text{Given that,}\\\\\cos \theta = - \dfrac 23\\\\\implies \cos^2 \theta = \dfrac 49\\\\\implies 1- \sin^2 \theta = \dfrac 49\\\\\implies \sin^2 \theta =1-\dfrac 49\\\\\implies \sin^2 \theta =\dfrac 59\\\\\\\text{Now,}\\\\\cot^2 \theta = \dfrac{\cos^2 \theta}{\sin^2 \theta} \\\\\\\implies \cot^2 \theta = \dfrac{\tfrac 49}{\tfrac 59}\\\\\\\implies \cot^2 \theta = \dfrac 49 \times \dfrac 95\\\\\\\implies \cot^2 \theta = \dfrac 45\\\\\\$

$\implies \cot \theta = \pm\sqrt{\dfrac 45} = \pm \dfrac 2{\sqrt 5}\\\\\\\text{Since}~ \theta ~ \text{lies in the second quadrant,} \cot \theta ~\text{will be negative.}\\\\\text{Hence,}~ \cot \theta = - \dfrac{2}{\sqrt 5}$

If you flip a coin and roll a 6-sided die, what is the probability that you will flip a heads and roll a 2 ?

katen-ka-za [31]

Answer:

1/12

Step-by-step explanation:

When you flip a coin, there are two possible outcomes. When you roll a die there are six possible outcomes. This means the chances of getting a heads is 1/2 and the chances of rolling a 2 are 1/6. To find the probability that both will occur, multiply the two probabilities: 1/6 * 1/2 = 1/12

Oxygen is being added to a canister which originally contained 5 cubic feet of the gas at

lesantik [10]

Answer:

The change is negative, since the volume in the final state is smaller than the volume in the initial state. 2.25 We express V for the ideal gas as a function of T , p and n: V (T , p, n) = ... each smooth part of the curve and add the integrals, used up yearly by living organisms, which means that even if the oxygen supply was.
