4. The point P(0.5, 0) lies on the curve y= cos Tz a. If Q is the point (r, cos rr), use your calculator to find the slope of the secant line PQ (correct to six decimal places) for the following values of ii. 0.4 iii. 0.49 iv. 0.499 V. 1 vi. 0.6 vii. 0.51 viii. 0.501 b. Using the results of part (a), guess the value of the slope of the tangent line to the curve at P (0.5, 0). c. Using the slope from part (b), find an equation of the tangent line to the curve at P (0.5, 0) d. Sketch the curve, two of the secant lines, and the tangent line. t in foet t seconds later is ito h
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
Please answer all of the questions. Elaborate and make clear the last graph because that is the one I am struggling most on. Thank you so much!
