- Can the average rate of change of a function be constant?The distribution of the height of males in the U.S. is roughly normally distributed with a mean of 70 inches and a standard deviation of 3 inches. (a) Draw a normal curve with the parameters labeled. (b) Shade the region on your drawing that represents the proportion of males in the U.S. that are 68 inches tall or taller. (c) Suppose the area under the normal curve to the right of x=74 is 0.0912. Provide two interpretations of this result.Find the area of the shaded region the graph to the right to pics IQ scores of adults and those scores are normally distributed with a mean of 100 and a standard deviation of 15.
- The "spring-like effect" in a golf club could be determined by measuring the coefficient of restitution (the ratio of the outbound velocity to the inbound velocity of a golf ball fired at the clubhead). Twelve randomly selected drivers produced by two clubmakers are tested and the coefficient of restitution measured. The data follow: Club 1: 0.8406, 0.8104, 0.8234, 0.8198, 0.8235, 0.8562, 0.8123, 0.7976, 0.8184, 0.8265, 0.7773, 0.7871 Club 2: 0.8305, 0.7905, 0.8352, 0.8380, 0.8145, 0.8465, 0.8244, 0.8014, 0.8309, 0.8405, 0.8256, 0.8476 Test the hypothesis that both brands of ball have equal mean overall distance. Use α = 0.05 and assume equal variances. Question: Reject H0 if t0 < ___ or if t0 > ___.The F-ratio is calculated by ______ different types of variability. dividing subtracting adding multiplyingFind the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15. Given points: between 102 and 124 are shaded.
- Describe the standard error of the point estimate S, and what it means? (for standard variation of your population)Dr. Johnson is interested in the difference in mean systolic blood pressure between groups. He performs analysis and finds a mean difference of 0.0005 mmHg in systolic blood pressure with a p value of 0.001. Dr. Johnson's findings are: a) statistically insignificant and practically significant b) statistically significant and practically significant c) statistically insignificant and practically insignificant d) statistically significant but practically insAbout ______% of the area is between z= -1 and z= 1 (or within 1 standard deviations of the mean).
- The IDOLE Company has two assembly lines in its Hamburg plant. Line A produces an average of 335 units per day with a standard deviation equal to 11units. Line B produces an average of 145 units per day with a standard deviation equal to 8 units. Based on this information using the coefficient of variation determine which line is relatively more consistent? Explain the answer by the information given and through the calculations involved in arriving at the answer.The height of waste bin manufactured by a factory for a garden have a normal distribution with mean as 1.25 m and standard deviation of 10 cm.
