QUESTION:

According to the National Sleep Foundation, children between the ages of 6 and 11 years should get 10 hours of sleep each night. In a survey of 57 parents of 6 to 11 year olds, it was found that the mean number of hours the children slept was 8.6 with a standard deviation of 3.1. Does the sample data suggest that 6 to 11 year olds are sleeping less than the required amount of time each night? Use the 0.10 level of significance.

PULL DOWN ANSWER CHOICES:

H0 & H1: or por & not equal to, = ,

test statistic: T0 or Z0 = _____

Since the P-value is GREATER or LESS than , DO NOT REJECT or REJECT the null hypothesis. There IS NOT or IS sufficient evidence to conclude that the mean number of hours of sleep that 6 to 11 year olds are getting each night is LESS THAN , GREATER THAN , DIFFERENT FROM, or EQUAL TO 10 hours.
