2) As you can see from the question, it says, "If the mean level of cadmium **exceeds** the allowable amount of X XXXXXXXXX per liter for a sanitary XXXXXXXX...". Therefore, XX are XXXXXXX XXX XXX values in our XXXX **XXXXX** our test XXXXX, or 1mg/X. Therefore we XXXX XXX a **XXXXX-XXXXXX test**. XXXX XXXX allow us to XXXX for XXX XXXXXX XXXX XXXXXX 1mg/X XXXX XXX part XX the distribution. ---
X) XXX XXXXXXXX XXXXXXXXXX, I XXXXXXX using the Simple XXXXXX Sampling method. XX is arguably the XXXX XXXXXX XXX easiest XX XXXXXXX. We only XXXX a XXXXXX population XX things we want XX XXXX daily, XXX therefore, doesn't XXXXXXXXXXX XXXX XX go XXXX XXXX XXXXXXXXXXX XXXXXXXX techniques. However, XXXX Simple Random Sampling, having a XXXXX sample size is XXXXXXXX to be representative XX the entire population of trucks. So, XXX XXXXXX Random XXXXXXXX, it does XXXXXX a lot how big the size of XXX XXXXXX XX. ---
4) First, I'll XXXXXXX XXXX a XXXX I error XXX Type II error are XXXXXXXXXXX, and XXXX explain it in XXXXXXX XX the XXXXXXX.
Type I Error: rejecting the XXXX XXXX it XX XXXX Type XX XXXXX: XXXX to XXXXXX the XXXX XXXX it XX false
So XXXXXXXXX the XXXXX part of the XXXXXXXX, XX we XXXXXX XXXX the XXXX levels XX XXXXXXX XXX XXXXXXX than X, therefore rejecting XXX null XXXXXXXXXX (which says the XXXX XXXXXX XX cadmium XXX equal to 1), then XX will XXXX a XXXX I XXXXX. If we XXXXXXXXXXXX decide that XXX mean levels XX cadmium are greater than 1, then XX force XXX XXXXXXX to XXXXX more XXXXX XXXXXXX XXX trucks XX a XXXXXXXX XXXX XX XXXXXXX away, when in XXXX, XX didn't XXXX to XX that.
Answering the XXXXXX XXXX XX the question, I XXXXXXX that a XXXX II XXXXX XX XXXX more XXXXXXX. This is XXXXXXX XX the accidentally sends XXXXXX farther XXXX and spends a little XXXX XXXXX, it's not XXX end XX the world. XXXXXXX, XX the XXXXXX are XXXXXXXXXX harmful XXXXXX XX XXXXXXX into a XXXXXXXX XXXX XXXX XXXXXXX't be, that can XXXX XXXXXXX implications XX XXX surrounding XXXXXXXXXX as well as XXXXXXXX the XXXXXXXXXXX. XXXX XX XXXXX is XXXXXXXXXXX XXXX harmful. ---
5) XXXXX a p-XXXXX XX 0.XX (any number XXXX XXXX X.XX) XX less than XXX alpha value XX 0.05, XX XXXXXX XXX null XXXXXXXXXX. There XX evidence XX XXXXXXX that XXX XXXX level of cadmium in the truckloads XXXXX XXXXXXXXX into XXX landfill exceeds the XXX/L XXXXX, XXX XXXXXX XXXXXXXXX be XXXXXXXXX in a XXXX XXXXXXXXXXX XXXXXXXX XXXXXXX XXXX.
