Answer:
any number equal to or less than -4
Step-by-step explanation:
x - 1 < -4
< represents that -4 is a larger number than x - 1. we know that -4 is a negative number, so anything below -4 would be less. x = -4 would be a good solution, but the reality is that any number equal to or less than -4 is the correct answer. I hope this helps!

Answer:

Step-by-step explanation:
If we assume that the number of arrivals is normally distributed and we don't know the population standard deviation, we can calculated a 95% confidence interval to estimate the mean value as:

where x' is the population mean value, x is the sample mean value, s is the sample standard deviation, n is the size of the sample,
is equal to 0.05 (it is calculated as: 1 - 0.95) and
is the t value with n-1 degrees of freedom that let a probability of
on the right tail.
So, replacing the mean of the sample by 49, the standard deviation of the sample by 17.38, n by 10 and
by 2.2621 we get:

Finally, the interval values that she get is:
