Given situation.
Research suggests that most people need at least 7 hours of sleep each night in order to function well
the next day. Some research suggests that lack of sleep can adversely affect health, memory, learning,
creativity, productivity, emotional stability, and even life expectancy. Suppose adults need 7.0 hours of sleep
per night. You as a researcher obtained a random sample of
adults, and the sleeping time for each
was recorded. The sample mean was x =
hours and assume o = 0.67 hours. Is there any
evidence to suggest that the mean sleeping time for adults is less than 7 hours? Use a = 0.05.
Show the steps in testing hypothesis.

National Sleep Foundation guidelines1 advise that healthy adults need between 7 and 9 hours of sleep per night. Babies, young children, and teens need even more sleep to enable their growth and development. People over 65 should also get 7 to 8 hours per night.Knowing the general recommendations for how much sleep you need is a first step. Then It’s important to reflect on your individual needs based on factors like your activity level and overall health. And finally, of course, it’s necessary to apply healthy sleep tips so that you can actually get the full night’s sleep that’s recommended
