Waiting times (in hours) at a popular restaurant are believed to be approximately normally distributed during busy periods. a sample of 20 customers revealed a mean waiting time of 1.58 hours with a sample standard deviation of 1.5 hours. construct a 95% confidence interval for the population mean waiting time.

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?

The distributive property allows you to say that 3(x − 1) = 3x −
