A doctor's office collected sample data for 25 patients, and found that they had to wait an average of 35 minutes with a sample standard deviation of 10 minutes, in order to see the doctor. (The wait times were also found to be normally distributed.) We are interested in calculating a 98% confidence interval for the average waiting time for the population of all patients. PART 2: What t value would be used to calculate the interval estimate (to 3...

Every day, patients arrive at the dentist’s office. If the Poisson distribution were applied to this process: a.) What would be an appropriate random variable? What would be the exponential-distribution counterpart to the random variable? b.)If the random discrete variable is Poisson distributed with λ = 10 patients per hour, and the corresponding exponential distribution has x = minutes until the next arrival, identify the mean of x and determine the following: 1. P(x less than or equal to 6)...

At CDE dental office, on average, 30 patients arrive every hour and are processed at the same rate. Patients wait in line for registration. On average, it takes 5 minutes for registration, not including waiting time. A dentist’s assistant sees a patient after registration and assigns the patient to one of the two tracks, one for routine cleanings and another for major treatments. On average, the dentist's assistant spends 20 minutes with each patient. On average, 2/3 (or 66.67%) of...

A random sample of 32 patients in a doctor’s office found that waiting times had a mean of 13 minutes with a standard deviation of 4.1 minutes. Based on this sample, a local doctor claims that the mean waiting time in their office is less than 15 minutes. At a 0.01 significance level, test the doctor's claim. Choose the correct Null & Alternative Hypothesis and Conclusion with appropriate justification: Select one: H0:μ=13 H1:μ<15 Since the P-Value is ≈0.41 and that...
