On average, a student takes 100 words/minute midway through an advanced court reporting course at the American Institute of Court Reporting. Assuming that the dictation speeds of the students are normally distributed and that the standard deviation is 20 words/minute, find the probability that a student randomly selected from the course can take dictation at the following speeds. (Round your answers to four decimal places.)

(a) more than 140 words/minute

(b) between 40 and 140 words/minute

(c) less than 40 words/minute

A person takes 15 minute showers in 100°F water using a 2.0 gallon per minute shower head. Ignoring losses, how many cubic feet of natural gas did the shower need if the house has a 40,000 BTU/hour water heater? The incoming water temperature is 50°F. Is it possible for this person to complete this shower without the water temperature dropping?

#1: Using traditional methods it takes 100 hours to receive an advanced driving license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher believes the new technique may reduce training time and decides to perform a hypothesis test. After performing the test on 190 students, the researcher fails to reject the null hypothesis at a 0.02 level of significance. #2: The director of research and development is testing a new drug. She wants to know...

The average reading speed of adult Americans is claimed to be 250 words per minute. The English department of a major American research university believes that this is not the case. They conduct a study using a simple random sample of 74 adult Americans and ﬁnd an average reading speed of 280 words per minute. Assume the population standard deviation is know to be 25 words per minute. Given the above information answer the following questions. Looking for null and...
