Step-by-step explanation:
Answer: The test statistic is t= -0.90.
Step-by-step explanation:
Since we have given that
n₁ = 50
n₂ = 25
![\bar{x_1}=3.02\\\\\bar{x_2}=3.04\\\\\sigma_1=0.08\\\\\sigma_2=0.06](https://tex.z-dn.net/?f=%5Cbar%7Bx_1%7D%3D3.02%5C%5C%5C%5C%5Cbar%7Bx_2%7D%3D3.04%5C%5C%5C%5C%5Csigma_1%3D0.08%5C%5C%5C%5C%5Csigma_2%3D0.06)
So, s would be
![s=\sqrt{\dfrac{n_1\sigma_1^2+n_2\sigma_2^2}{n_1+n_2-2}}\\\\s=\sqrt{\dfrac{50\times 0.08^2+25\times 0.06^2}{50+25-2}}\\\\s=0.075](https://tex.z-dn.net/?f=s%3D%5Csqrt%7B%5Cdfrac%7Bn_1%5Csigma_1%5E2%2Bn_2%5Csigma_2%5E2%7D%7Bn_1%2Bn_2-2%7D%7D%5C%5C%5C%5Cs%3D%5Csqrt%7B%5Cdfrac%7B50%5Ctimes%200.08%5E2%2B25%5Ctimes%200.06%5E2%7D%7B50%2B25-2%7D%7D%5C%5C%5C%5Cs%3D0.075)
So, the value of test statistic would be
![t=\dfrac{\bar{x_1}-\bar{x_2}}{s(\dfrac{1}{n_1}+\dfrac{1}{n_2})}\\t=\dfrac{3.02-3.04}{0.074(\dfrac{1}{50}+\dfrac{1}{25})}\\\\t=\dfrac{-0.04}{0.074(0.02+0.04)}\\\\t=\dfrac{-0.04}{0.044}\\\\t=-0.90](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B%5Cbar%7Bx_1%7D-%5Cbar%7Bx_2%7D%7D%7Bs%28%5Cdfrac%7B1%7D%7Bn_1%7D%2B%5Cdfrac%7B1%7D%7Bn_2%7D%29%7D%5C%5Ct%3D%5Cdfrac%7B3.02-3.04%7D%7B0.074%28%5Cdfrac%7B1%7D%7B50%7D%2B%5Cdfrac%7B1%7D%7B25%7D%29%7D%5C%5C%5C%5Ct%3D%5Cdfrac%7B-0.04%7D%7B0.074%280.02%2B0.04%29%7D%5C%5C%5C%5Ct%3D%5Cdfrac%7B-0.04%7D%7B0.044%7D%5C%5C%5C%5Ct%3D-0.90)
Hence, the test statistic is t= -0.90.

Answer:</h3><h3>If you know one ratio in a proportion , you can use that information to find values in the other equivalent ratio. </h3>
Answer:
Arrange the variables to y intercept form: y=-x+2. We have the slope is -1, and the y intercept is 2. You should be able to draw a line from here.
