2) As you can see from the question, it says, "If the mean level of cadmium **exceeds** the allowable amount of 1 milligram XXX liter for a sanitary landfill...". XXXXXXXXX, we are XXXXXXX for the XXXXXX in XXX XXXX **XXXXX** XXX test XXXXX, or 1mg/X. Therefore XX XXXX XXX a **XXXXX-XXXXXX XXXX**. This will allow us XX look XXX the XXXXXX that exceed XXX/L XXXX XXX part of the XXXXXXXXXXXX. ---
3) For XXXXXXXX techniques, I XXXXXXX XXXXX XXX XXXXXX XXXXXX Sampling XXXXXX. XX is arguably XXX most common and easiest to conduct. We only XXXX a single population XX XXXXXX XX XXXX to test XXXXX, and therefore, doesn't necessitate XXXX we XX XXXX more XXXXXXXXXXX sampling XXXXXXXXXX. However, with Simple Random XXXXXXXX, having a XXXXX XXXXXX size XX critical XX be XXXXXXXXXXXXXX XX the XXXXXX XXXXXXXXXX of XXXXXX. XX, for Simple XXXXXX Sampling, it does matter a lot how XXX the XXXX XX XXX XXXXXX XX. ---
4) XXXXX, I'll XXXXXXX XXXX a XXXX I XXXXX and Type XX XXXXX XXX arbitrarily, and XXXX explain it in context XX XXX problem.
XXXX I XXXXX: XXXXXXXXX the XXXX when it is true XXXX XX XXXXX: fail XX XXXXXX the XXXX when it is false
So XXXXXXXXX the first part of XXX question, XX XX decide that the XXXX levels XX cadmium XXX XXXXXXX than X, therefore XXXXXXXXX the XXXX hypothesis (XXXXX says XXX mean XXXXXX XX XXXXXXX are XXXXX to 1), then we XXXX have a XXXX I error. XX XX accidentally XXXXXX XXXX XXX mean levels XX XXXXXXX are XXXXXXX XXXX 1, then XX XXXXX XXX company to spend more money XXXXXXX the trucks XX a XXXXXXXX that is farther away, XXXX in fact, XX didn't XXXX XX do XXXX.
XXXXXXXXX the XXXXXX XXXX of the question, I XXXXXXX XXXX a Type II error XX XXXX more serious. XXXX XX XXXXXXX XX the XXXXXXXXXXXX XXXXX trucks XXXXXXX XXXX and spends a little more XXXXX, it's not the XXX XX the XXXXX. However, XX the trucks are XXXXXXXXXX harmful XXXXXX of XXXXXXX into a XXXXXXXX when XXXX XXXXXXX't be, XXXX XXX have XXXXXXX implications on the XXXXXXXXXXX XXXXXXXXXX as XXXX as damaging the environment. XXXX II XXXXX is XXXXXXXXXXX XXXX XXXXXXX. ---
X) Since a p-value of 0.XX (any number less XXXX X.XX) is less XXXX XXX XXXXX XXXXX of X.XX, XX XXXXXX the XXXX XXXXXXXXXX. There is evidence to suggest XXXX the mean XXXXX XX XXXXXXX in XXX XXXXXXXXXX XXXXX XXXXXXXXX XXXX XXX XXXXXXXX XXXXXXX the XXX/L XXXXX, XXX should XXXXXXXXX XX deposited in a more XXXXXXXXXXX XXXXXXXX farther XXXX.
