A cable company advertises short wait times for customer service calls. The graph shows the wait times (in seconds) for asample of customers. Based on the data given, if a customer is selected at random, find the probability thatNumber of Customers vs. Wait Time, x120 sx< 150x< 3090 sx< 120-60 sx<90515322130 sx< 60a. The customer will wait less than 30 sec.b. The customer will wait at least 30 sec.C. The customer will wait at least 90 sec but less than 120 sec.d. The customer will wait more than 150 sec.2.

Given: The graph of the wait times (in seconds) for a sample of customers service calls is as…

A recent survey of 1040 U.S. adults selected at random showed that 634 consider the occupation of firefighter to have very great prestige. Estimate the probability (to the nearest hundredth) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige.Step 1Recall that the probability of an event based on relative frequency uses the formulaprobability of event = relative frequency = fn,where f is the frequency of the event occurrence in a sample of n observations. A total of 1040 people were surveyed and 634 considered the occupation of firefighter to have very great prestige. Therefore, the sample size is n = . The event of interest is that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige. Therefore, the frequency f is equal to the number of adults who the occupation of firefighter has very great prestige, so f = (0.6096 answer is incorrect.) .
The mean percent of childhood asthma prevalence in 43 cities is 2.07%. A random sample of 33 of these cities is selected.

Assuming a population is normally distributed, calculate the probability that a random member of the population falls between 3 standard deviations below the mean and 1 standard deviation below the mean. In other words in mathematical notation: P(-3 < z < -1) Enter your answer in decimal form. For example, 75% should be entered as 0.75.
A certain disease has an incidence rate of 0.2%. The false negative rate is 8%, and the false positive rate is 3%. Calculate the probability that a person who tests positive actually has the disease. 0.0848 Note: The incidence rate is the probability that a random person gets the disease. The false negative rate is the probability of getting a negative result given that the person has the disease. The false positive rate is the probability of getting a positive result given that the person does not have the disease.
