A survey of 959 teenagers between the ages of 13 and 18 found that 67% agree that people who practice good business ethics are more successful that those who do not. a. Calculate the 95% confidence interval estimate for the true population proportion, p, given by the survey information. b. What is the largest possible sample size needed to estimate the true population proportion, p, within a margin of error of # 0.02 with a confidence level of 90% if there was no prior knowledge concerning the proportion of respondents who agree with the survey's question. c. If the survey in part a had a margin of error of 0.04, determine the level of confidence that was used in estimating the population proportion if there was no prior knowledge concerning the percentage of teenagers who would respond as they did. a. The confidence interval estimate is Sps (Round to three decimal places as needed.) b. The largest possible sample size that would be needed is (Round up to the nearest whole number as needed.) c. The level of confidence was %. (Round to one decimal place as needed.)

35) First consider the left loop: a) What is the induced ε in the left loop? What is the magnitude of the current in the left loop? b) How is the flux ɸB changing (increasing or decreasing) in the left loop? c) What is the direction of the current in the left loop (CW or CCW)? Remember: the induced current creates a magnetic field that opposes how the flux is changing. So is the current going up the bar, or down the bar? Now consider the right loop: d) What is the induced ε in the right loop? What is the magnitude of the current in the right loop? e) How is the flux ɸB changing (increasing or decreasing) in the right loop? f) What is the direction of the current in the right loop (CW or CCW)? Remember: the induced current creates a magnetic field that opposes how the flux is changing. So is the current going up the bar, or down the bar? g) What is the power used by each resistor R1 and R2? What is the total power used by both resistors? h) Using the direction of the current in the bar, (what is Itotal in the bar?) determine the magnitude and direction of the FB on the bar. Don’t round this number off. This much force must be applied to the bar, Fapp, (in the opposite direction) to keep the bar moving with a constant speed. i) What is the power that must be applied to the bar? This number should be familiar

Two vectors, \(\vec{r}\) and \(\vec{s}\) lie in the xy plane. Their magnitudes are 3.85 and 7.35 units, respectively, and their directions are 295° and 33.0°, respectively, as measured counterclockwise from the positive x axis. What are the values of (a) \(\vec{r} \cdot \vec{s}\) and (b) \(|\vec{r} \times \vec{s}|\)? (a) Number Units This answer has no units (b) Number 27.8 Units This answer has no units

Part A A potter's wheel is rotating around a vertical axis through its center at a frequency of 2.0 rev/s. The wheel can be considered a uniform disk of mass 4.7 kg and diameter 0.34 m. The potter then throws a 2.9-kg chunk of clay, approximately shaped as a flat disk of radius 7.0 cm, onto the center of the rotating wheel. What is the frequency of the wheel after the clay sticks to it? Ignore friction. Express your answer using two significant figures. f = 1.7 rev/s
