a. To determine The probability that the cell phone was using color code 5. Explanation Given info: Different color codes accessed by the cell phone were monitored and recorded during a sample driving trip that involved crossing from one station to another. The table showing the number of times each color code was accessed for two identical driving trips, each using a different cell phone model. Calculation: Define the events A as the cell phone of model 1 and B as the cell phone of model 2. The events are: A : { Model 1 } B :< b. To determine The probability that the cell phone was using color code 5 or color code 0. c. To determine The probability that the cell phone was Model 2 and the color code was 0.

Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as p…

6.4. The data shown in Table 6E.1 are x and R values for 24 samples of size n = 5 taken from a process producing bearings. The measurements are made on the inside diameter of the bearing, with only the last three decimals recorded (i.e., 34.5 should be 0.50345).

An automobile manufacturer wishes to monitor the number of nonconformities in a subassembly area producing manual transmissions. The inspection unit is defined as four transmissions, and data from 16 samples (each of size 4) are shown in Table 7E.11. a. Set up a control chart for nonconformities per unit. A u chart of average number of nonconformities per unit is appropriate, with n = 4 transmissions in each inspection. b. Do these data come from a controlled process? If not, assume that assignable causes can be found for all out-of-control points and calculate the revised control chart parameters. Draw x-bar control chart and R chart c. Suppose the inspection unit is redefined as eight transmissions. Design an appropriate control chart for monitoring future production

The data in Table 7E.3 give the number of nonconforming bearing and seal assemblies in samples of size 100. Construct a fraction nonconforming control chart for these data. If any points plot out of control, assume that assignable causes can be found and determine the revised control limits. n=100;" " m=20;" " ∑_(i=1)^m▒D_i =117;" " p ̄=(∑_(i=1)^m▒D_i )/mn "UC" "L" _p=p ̄+3√((p ̄(1-p ̄))/n) "LC" "L" _p=p ̄-3√((p ̄(1-p ̄))/n) Draw x-bar control chart and R chart Remove the data that are not in control and recalculate UCL, CL, LCL and redraw control chart.
