How do I state the 1. null hypothesis Ho (nothing happened, there is no difference) 2. alternative hypothesis Ha (something happened, there is a difference) in each of the folowing cases. (a)The diameter of a spindle in a small motor is supposed to be 5 mm. If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of motors to determine whether the mean diameter has moved away from the target. (b)Census Bureau data show that the mean household income in the area served by a hospital is $42,500 per year. A market research firm questions patients at the hospital. The researchers suspect the mean household income of patients is higher than that of the general population.

I need to know how to calculate the probabililty when you have the following information 25 random outcomes possible outcomes is either pass or fail 8% failure rate production shutdown each week GM would like to shutdown production no more than 1% of the time after much debate GM has decided to shut down after 5 boxes in a weekly sample fail
Español We want to conduct a hypothesis test of the claim that the population mean time it takes drivers to react following the application of brakes by the driver in front of them is less than 1.9 seconds. So, we choose a random sample of reaction time measurements. The sample has a mean of 1.8 seconds and a standard deviation of 0.5 seconds. For each of the following sampling scenarios, choose an appropriate test statistic for our hypothesis test on the population mean. Then calculate that statistic. Round your answers to two decimal places. (a) The sample has size 17, and it is from a normally distributed population with an unknown standard deviation. O z =D] %3D %3D O It is unclear which test statistic to use. Aa (b) The sample has size 95, and it is from a non-normally distributed population with a known standard deviation of 0.50. z =D0 %3D It is unclear which test statistic to use.
How to Identify the test statistic
What is the p-value of a left-tailed one-mean hypothesis test, with a test statistic of z0=−1.19? Use a p-value rounded to 3 decimal places. Here is a portion of the Standard Normal Table. To read the Standard Normal table, match the ones and tenths digits of the z-value in the first column with the correct hundredths digit in the first row. z 0.00 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 -1.4 0.081 0.079 0.078 0.076 0.075 0.074 0.072 0.071 0.069 0.068 -1.3 0.097 0.095 0.093 0.092 0.090 0.089 0.087 0.085 0.084 0.082 -1.2 0.115 0.113 0.111 0.109 0.107 0.106 0.104 0.102 0.100 0.099 -1.1 0.136 0.133 0.131 0.129 0.127 0.125 0.123 0.121 0.119 0.117 -1.0 0.159 0.156 0.154 0.152 0.149 0.147 0.145 0.142 0.140 0.138
Working Backwards from the Confidence Interval to Find the Sample MeanSometimes when we read statistical studies, only the confidence interval is stated; however, if the confidence interval is known, we can work backwards to find the sample mean. Suppose a sample mean was used to construct an interval of (42,49). What was the value of the sample mean?
Explain what chi-squared test of independence is. What is the underlying assumption? What is the test statistic and what is its asymptotic distribution? How the hypothesis is formulated and what are the expected outcomes? What is the criterion for rejecting the null hypothesis? How is the p value evaluated? Provide a hypothetical formulation of test of independence. I do not need the first three subparts answered. you already answered the first three subparts im resumiting to have the other parts answered.
