A fast-food franchiser is considering building a restaurant at a certain location. Based on financial analyses, a site is acceptable only if the number of pedestrians passing the location averages more than 100 per hour. The number of pedestrians observed for each of 40 hours was recorded. Assuming that the population standard deviation is known to be 16, Estimate with 95% confidence the mean number of pedestrians passing the location. Can we conclude at the 5% significance level that the...

Question 8 The mean life of a certain brand of auto batteries is 44 months with a standard deviation of 3 months. Assume that the lives of all auto batteries of this brand have a bell-shaped distribution. Using the empirical rule, find the percentage of auto batteries of this brand that have a life of 38 to 50 months. Round your answer to one decimal place the tolerance is +/-2%

You are given: Each day, the number of of visitors of an Internet search engine has a distribution with mean 2 million and standard deviation 300000. The number of searches by each visitor each day has a distribution with mean 5 and variance 4. The number of visitors of the search engine each day and the number of searches by the visitors are independent. Using normal approximation for the total number of searches, determine the least number of whole days...

3. Suppose we observe temperatures in several cities at noon on a particular day. The mean observed temperature is 20 degrees Centigrade; the standard deviation is 5 degrees. a) Degrees Fahrenheit are related to degrees Centigrade according to the formula (F = 32+1.8C). Suppose we were to convert the observed temperatures to degrees Fahrenheit. What would the mean temperature be in degrees Fahrenheit? What would the standard deviation be? b) Temperatures can be expressed in standard units. Suppose the temperature...

It has long been stated that the mean temperature of humans is
98.6 degrees°F. However, two researchers currently involved in the
subject thought that the mean temperature of humans is less than
98.6 degrees°F. They measured the temperatures of 50 healthy adults
1 to 4 times daily for 3 days, obtaining 225 measurements. The
sample data resulted in a sample mean of 98.3 degrees°F and a
sample standard deviation of 11 degrees°F. Use the P-value
approach to conduct a hypothesis...
