Select the margin of error that corresponds to the sample mean that corresponds to each population: a population mean of 0.45, a standard deviation of 0.001, and margin of error of 0.5%

30 points! i am confused. what does it mean by game time? you can use a table of random numbers or a random number generator to create random samples. also, you can obtain random samples directly using wolframalpha.com. for example, typing in randomsample[{1,2,3,4,5},2] will give you a sample of size 2 from the list {1,2,3,4,5}. a sample result is {1,5}. refreshing the page will generate a new random sample of size 2. 2. create five random samples of size two from the population. record the game times for the samples and calculate the mean game time of each sample. 3. create 5 random samples of size 11 from the population. record the game times for the samples and calculate the mean game time of each sample.

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

Can someone me with my math problem pls my teacher is on my back about this
