Why did the Republicans in Congress feel that the Fourteenth Amendment was necessary?

They did it to protect the civil rights act from being overturned by the south. That is not one of the choices but that is what happened. They made it so that everyone is equal and that whites would not judge blacks. So I would say that C. is the correct answer.

Answer:

The test statistic for testing if the proportion of high-altitude vehicles exceeding the standard is greater than the proportion of low-altitude vehicles exceeding the standard is 3.234.

Step-by-step explanation:

We are given that in a random sample of 380 cars driven at low altitudes, 42 of them exceeded a standard of 10 grams of particulate pollution per gallon of fuel consumed.

In an independent random sample of 90 cars driven at high altitudes, 24 of them exceeded the standard.

Let $p_1$ = population proportion of cars driven at high altitudes who exceeded a standard of 10 grams.

$p_2$ = population proportion of cars driven at low altitudes who exceeded a standard of 10 grams.

So, Null Hypothesis, $H_0$ : $p_1\leq p_2$ {means that the proportion of high-altitude vehicles exceeding the standard is smaller than or equal to the proportion of low-altitude vehicles exceeding the standard}

Alternate Hypothesis, $H_A$ : $p_1>p_2$ {means that the proportion of high-altitude vehicles exceeding the standard is greater than the proportion of low-altitude vehicles exceeding the standard}
