Many people live under a lot of stress and various time constraints. Consequently, some people run out of the house without their keys and are locked out. Rather than break into their own home, most people in these circumstances call a locksmith. In 2018, the mean service charge for a locksmith was $181.00. A random sample of 26 locksmith service charges in Black Springs, Arkansas, was obtained. The sample mean & was $191.33. Assume that the underlying population distribution is normal and that the standard deviation is o = 24. Is there any evidence to suggest that the mean locksmith service charge in this city is greater than $181?
