innovative children’s toys which includes the Weather Teddy. The Weather Teddy has a built-in barometer that provides one of five standard responses about the weather when a child presses the teddy bear’s hand. The company recently reached out to our team to prepare a managerial report addressing, but not limited to, the following issues: normal probability distribution in relation to demand approximation, the probability of stock-outs for certain quantities and the projected profits associated with

Balance($) 1638 3890 2 Due to the bell-shaped curvature in the graph shown above, the customer’s credit balance will show a normal distribution. The highest frequency of credit from the customers is in the $4000.00 range, showing that most of the customers will classify in this range of credit balances. The mean for the credit balance is $3,970.00. The standard deviation is $932.00. The 25% quartile of frequency of customer credit balance is $3,109.00, the median $4,090.00, and the 75% quartile

Statistics in Economics The Rivalry: Wins per Season Phillies vs. Mets Throughout the years two teams laid the groundwork for what would be considered one of the greatest rivalries of all time. Baseball is America’s pastime and one of my favorite sports. I decided to do an in-depth statistical analysis of both team’s histories regarding wins since 1965. Surprisingly both teams, the Philadelphia Phillies and the New York Mets, have strong numbers but the Phillies came out on top when comparing

Explain when a z-test would be appropriate over a t-test. A Z-test is any statistical test for which the distribution of the test statistic under the null hypothesis can be approximated by a normal distribution. Because of the central limit theorem, many test statistics are approximately normally distributed for large samples. For each significance level, the Z-test has a single critical value (for example, 1.96 for 5% two tailed) which makes it more convenient than the Student's t-test which has

mChapter 5 Distribution – Exercise Answer Q1 a) P(Z < 1.47) = 0.9292 b) P(Z > 1.74) = 1 – 0.9591 = 0.0409 c) P(1.47 < Z < 1.74) = 0.9591 – 0.9292 = 0.0299 d) P(Z < 1.47) + P(Z > 1.74) = 0.9292 + (1 – 0.9591) = 0.9701 Q2 a) P(– 1.47 < Z < 1.74) = 0.9591 – 0.0708 = 0.8883 b) P(Z < – 1.47) + P(Z > 1.74) = 0.0708 + 0.0409 = 0.1117 c) If P(Z > A) = 0.025, P(Z < A) = 0.975. A = + 1.96. d) If P(–A < Z < A) = 0.6826, P(Z < A) = 0.8413. So 68.26% of the area is captured between –A = – 1.00 and A = + 1.00
