Running Speed A man is running around a circular track that is 200 m in circumference. An observer uses a stopwatch to record the runner’s time at the each of each lap, obtaining the data in the following table. (a) What was the man’s average speed (rate) between 68 s and 152 s? (b) What was the man’s average speed between 263 s and 412 s? (c) Calculate the man’s speed for cadi lap, Is he slowing down, speeding up, or neither?
Arm circumferences (cm) and heights (cm) are measured from randomly selected adult females. The 146pairs of measurements yield x=34.69cm, y=163.25cm, r=0.075, P-value=0.368, and y=157+0.1826x. Find the best predicted value of y (height) given an adult female with an arm circumference of 40.0cm. Let the predictor variable x be arm circumference and the response variable y be height. Use a 0.05 significance level. The best predicted value is ____cm.
d) Prepare the scatter diagram and insert the trendline or line of best-fit. Use a scale of 2 cm to represent 1,000 units on the x-axis & 2 cm to represent $50,000 on the yaxis.e) Using the line of best-fit, determine the company’s fixed cost per month and the variable cost per unit. (Use 0 & 5,000 units.)f) Which of the two methods appear more appropriate? Explain your answer

The relationship between IQ level and exam score was estimated as below in a linear format. (IQ level and exam scores are both measured in points) Exam score = 1.38 * IQ level - 67.43 (The p-value for the coefficient of IQ level is 0.04.) Base on the above equation, which of the following statements are true? (Select all that apply. There can be more than one answer.) The expected exam score of a person with an IQ level of 100 points is 70.57 The expected exam score of a person with an IQ level of 0 points is 1.38 points As a person’s IQ level increases by 1 point, his or her exam score is expected to increase by 1.38
ASAP!! The owner of the ABC garment is interested to study the wastage of the factory. Factory is running in two shifts (morning and evening). The value of the monthly wastage of the material shift wise is given in the data file. The manager told to the owner that on average, the value of monthly (both shifts) wastage is Rs. 4500. The owner feels that the wastage is more than the value which is communicated by the manager; therefore, he gives the data of the last few months (given below) to you as statistician and assigns the following three tasks: Morning Shift 4227 4489 4417 4392 3943 3970 4405 4990 4444 4405 4398 4152 Evening Shift 3366 2964 3043 3804 3721 3675 3504 3236 3955 3420 Task # 1: To test the manager’s claim at 0.05 level of significance. Task # 2: To test the equality of mean wastage in two shifts, assume the variances are equal at 0.05 level of significance.…
