Part (1) What is the p-value? (Round your answer to four decimal places.) Enter a number. Part (g) ⒸPart (h) Part (1) Explain what the p-value means for this problem. O If Ho is true, then there is a chance equal to the p-value that the sample mean salary of mechanical engineers is at least $800 less than the sample mean salary of electrical engineers. O If H, is false, then there is a chance equal to the p-value that the sample mean salary of mechanical engineers is $800 more than the sample mean salary of electrical engineers. O If He is false, then there is a chance equall to the p-value that the sample mean salary of mechanical engineers is at least $800 less than the sample mean salary of electrical engineers. O If Ho is true, then there is a chance equall to the p-value that the sample mean salary of mechanical engineers is $800 more than the sample mean salary of electrical engineers. Submit Answer to two Explain how you determined which distribution to use. O The t-distribution will be used because the samples are dependent. The standard normal distribution will be used because the samples involve the difference in proportions. O The standard normal distribution will be used because the samples are independent and the population standard deviation is known. O The t-distribution will be used because the samples are independent and the population standard deviation is not known.
