Hi By this way I think you miss to steps. I mean after 32 steps she has : 78.40 - (32*7.29) + (32*5) = 5.12 Ok right now she has not enough money to buy another one, but at the beginning the week she will have 10.12 and it is more tahn 7.29! So I think the final answer is 34 week. After that she will have 0.54 $. 78.40 - (32*7.29) + (34*5) = 0.54 $. This happens because: Receiving money in your pocket and paying for buying a magazine do not have time priority.
Hello Professor. I am a Mater's student and not having clear background of MATLAB so are these lectures complete to get a basic command over MATLAB as I am going to invest my time in it for a complete day or two .
First of all thanks for the great content - the explanations and examples are very good. I have a methodological question about the varience comparison example. Why H0 hypothesis is that the variences are equals? As explained in previous lectures H0 should be "not wanted" hypothesis. In this case, you couldn't reject H0, but it should NOT be a reason to accept it as seems to follow from from the last part of the video. Actually H0 hypothesis should be that the variances are NOT equal., and according to your computation the resulting p-value of this hypothesis will be above 0.2, so the hypothesis that variances are NOT equal can't be reject. Am I missing something?
The y-axis label in the bar graph says "heart rate reduction %", so if I'm not mistaken, the confidence intervals actually suggest that the new drug is more effective.
Is there an example on how to make this in a loop? I'm currently struggling with it. I dont understand how to tell matlab to create a 4x4 matrix of k dimensions. When I read it out only the first dimension works.
Thanks for video, Can ı ask you one question , How do I perform prelocation when creating an array using a for loop? for example Vcruise=[]; HPreq=[]; speedvalue=160 (maybe much more big values for other operations) ; for i=1:1:speedvalue Vcruise=[Vcruise,i]; ........ Ptotal_fwd=.... ...... HPreq=[HPreq,PTotal_fwd]; end and some graphical operations
