Answer:
The true mean it probably could be larger, smaller, or equal to 22
Step-by-step explanation:
False.
By definition the sample mean is defined as:
For this case the value for the sample size is n =190 and the calculated sample mean is . This value represent the sample and for this case we can't assume that this value represent at all the population as the population mean since we probably have variability from the data of the students at City College.
So we can conclude that the true mean it probably could be larger, smaller, or equal to 22
The answer is y = -5/7x + 4/7! The first step is to subtract the 5x so it’s on the other side of the equal sign. So now the equation is 7y = -5x + 4. Then divide each of them for 7
600 + 400 milliliters = 1,000 milliliters.
However, the question is asking how many liters she drank. 1 liter = 1,000 milliliters, so that means Cathy drank 1 liter of water.
