Because our brains can process upwards of 400 words per minute and humans can only speak at about 100 some words per minute we are often distracted when trying to listen.  

A beam has dimensions of b = 14 in., h = 22 in., and d = 19.5 in. and is reinforced with 3 No. 7 bars. The concrete strength is 5,500 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the tensile force T in the reinforcement.

This child’s mother wants no more than 3 shots given today (assume not are combined); therefore, based on common recommendations your best plan for immunizations today would be:

(05.01 LC)  Tiara, a quality assurance inspector at a chocolate factory, checks for product quality using a random sample of 18 pieces of chocolate from a batch of 60, with 17 white chocolates and 43 dark chocolates. Let p̂ be the proportion of white chocolates in the sample. Part A: Is the 10% condition met in this case? Justify your answer. (5 points) Part B: Is the Normal condition met in this case? Justify your answer. (5 points) (10 points)

(04.06 MC)  The grades on the last history exam had a mean of 80%. Assume the population of grades on history exams is known to be distributed Normally, with a standard deviation of 5%. Approximately what percent of students earn a score between 70% and 80%? (4 points)

(05.04 HC)  A program was created to randomly choose customers at a shoe store to receive a discount. The program claims 15% of the receipts will get a discount in the long run. The manager of the shoe store is skeptical and believes the program’s calculations are incorrect. She selects a random sample and finds that 12% received the discount. The confidence interval is 0.12 ± 0.05 with all conditions for inference met.Part A: Using the given confidence interval, is it statistically evident that the program is not working? Explain. (3 points)Part B: Is it statistically evident from the confidence interval that the program creates the discount with a 0.15 probability? Explain. (2 points)Part C: Another random sample of receipts is taken. This sample is six times the size of the original. Twelve percent of the receipts in the second sample received the discount. What is the value of margin of error based on the second sample with the same confidence level as the original interval? (2 points)Part D: Using the margin of error from the second sample in part C, is the program working as planned? Explain. (3 points) (10 points)
