Maximum Contaminant Levels (MCLs) are regulations on water quality set by the United States Environmental Protection Agency. Researchers measured the Chloramines MCLs (in mg/L) of water samples from random locations of each of two wells. The data are given below. Sample sizeSample meanSample sdWell A153.7 0.3Well B193.40.6Assume normal populations with equal variance and construct a 95% confidence interval for the difference in mean MCLs levels. Find the upper bound of the confidence interval (round off to second decimal place).

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.

Jace wrote a sentence as an equation. 56 is 14 more than a number. 14+ = 56 which statement best describes jace's work? jace is not correct. the phrase more than suggests using the symbol > and jace did not use that symbol. jace is not correct. he was correct to use addition, but the equation should be 56+ p = 14 jace is not correct. the first number in the sentence is 56, so the equation should start with 56. jace is correct. the phrase more than suggests addition, so jace showed that 14 plus a variable equals 56. o
