Explain the way in which racial or ethnic bias played a role in a specific change (either positive or negative) in the law related to: voting rights, tribal rights, or immigration. (Choose and discuss only one of these.) In the alternative, explain the way in which racial or ethnic bias impeded or prevented legal change in one of these areas of law. Make sure you:identify the law or laws you are discussingdescribe the racial or ethnic bias and against whom that bias was directedexplain how racial or ethnic bias influenced or prevented legal changeanalyze the impact of that racial or ethnic bias on this area of law in general.

An electrical engineer is checking whether a digital scale used in a manufacturing process is properly calibrated. The scale is designed to measure a standard reference weight of 1000 g. If the scale is calibrated correctly, the true mean of repeated measurements should equal 1000 g. The engineer weighs the reference mass 60 times and observes: Sample mean: x = 1000 . 6 g Known population standard deviation: σ = 2 . 0 g At a significance level of ⍺ = 0.01, a one‑sample z‑test was performed using statistical software to determine whether the data provide evidence that the scale is out of calibration. The output is shown below. Software Output One-Sample Z null hypothesis: true mean is equal to 1000 (scale is properly calibrated) alternative hypothesis: true mean is not equal to 1000 (scale is not properly calibrated) Variable     N    Mean    StDev   SE Mean              95% CI               Z-Value   P-Value Weight        60  1000.6     2.00       0.258       (1000.094, 1001.106)     2.33         0.02 Based on the fixed-level method (utilizing rejection regions), select the best statistical conclusion.

An engineer checks whether a pressure sensor is properly calibrated. Six repeated measurements are taken. The population standard deviation is unknown, but the engineer believes the measurement errors are approximately normally distributed.Select both the appropriate hypothesis test and the best justification.
