What Is the sample linear correlation coefficient (rs)?

The technique for automated scaling has to be defined.

Approximately what percentage of people would have scores lower than an individual with a z-score of 1.65 in a normally distributed population? Approximately 95% 50% Approximately 5% Not possible to calculate (mean and standard deviation are not given)

Given the following values (200, 400, 800, 1000, 2000): Calculate their mean, variance, and standard deviation. Normalize them using min-max normalization with and . Normalize them using z-score.

What does the z-score of a data point tell us? Group of answer choices How many standard deviations a number is from the mean. How many IQR the max and min are from the mean. How far a number is from the mean. How many IQR a number is from the mean.

Can you help me write the code for this MATLAB assignment?

Consider the following table that contains the IDs of 12 participants and their crash- avoidance reaction times (in milliseconds) on four tests. Two tests were done during the day in daylight and two tests were done at night with reduced lighting. Crash-avoidance Reaction Time (ms) Participant Day Night ID Test 1 Test 2 Test 3 Test 4 9001 887 838 765 648 9002 680 491 953 767 9003 662 553 985 696 9004 789 526 581 770 9005 508 451 688 714 9006 566 633 856 642 9007 656 747 846 718 9008 776 491 944 604 9009 770 672 814 617 9010 333 432 591 602 9011 730 593 796 700 9012 496 404 846 892 rt.xisx in the This question has multiple parts. Create output to MATLAB's command window exactly as shown, except replacing xxxx with actual values, as instructed. You may use the disp command, but not the fprintf command If you have difficulty with the alignment or formatting of numeric output, add the command format shortg near the top of your solution. In your solution, put the following MATLAB statements…

Analyze The average annual temperature is about 25 °C in both Yemen and the Democratic Republic of Congo. Why do the two places look so different?

What is the mean of Linear Correlation ? if r = 0 has strong linear correlation it does mean has strong linear relationship?

Given that the mean for a data set is 24.8 and the standard deviation is 2.3, find the z-score of the number 27 in this set. Group of answer choices -0.96 0.96 0.83 1.00
