I have been trying to figure answer this question What is the value of hBwith the correct number of significant figures? ____ cm. Could you please help me by showing me the equation to figure out the problem. I have already found the sample standard deviation, error and the mean which i will be attaching.
What is the sample mean height from University A? ____ cm (Enter at least 4 signicant gures.) 161258 Question 2 What is the sample standard deviation of the heights from University A? ____ cm [Enter at least 3 signicant gures.) 33'? Question 3 What is the standard error of the heights from University A? ____ cm (Enter at least 3 signicant gures.) 1.243 We report the measured value for the height of students at UniversityA as (h); :l: 6h\" ) (XIII1 were 115 is the best estimate, and 5h .1 is the uncertainty. Statistical Analysis Exercise: Comparing Heights One of the things that we do often in physics is to compare measurements, but given what we know about the variability of measurements, the question bears asking, "How close is close enough?" Put another way. if two people report measurements of the same propertyperhaps by different methodshow can they tell if they agree or not? Enough talk. let's come up with a concrete example. Suppose we want to determine whether there is a difference in heights between students at University A, University B, and University C. We do not have the resources to measure the height of each student at each university, but we are able to measure the heights of 50 randomly-selected students from each university. Our question is this: Are the students at University A, University B, and University C the same height? Data Data from the three universities is given below.
