    I Calculate the mean, variance, stdev, and CV with 2 methods: check answers

    Hello! Yes I use the midpoint, but i didn't make the bins to have a lower & upper limit except for the last bin, so for the previous bins, the midpoint is the data value itself.

    I Calculate the mean, variance, stdev, and CV with 2 methods: check answers

    Thank you so much for answering! I see, that makes sense, 17.5 doesn't seem to be the best number. Does it mean I cannot use the midpoint in this case? Or should I calculate the average or mean of this data group and use it as the midpoint? In an example in class, see that the professor left the...

    Backcross vs Testcross difference: Research on mitochondrial genes

    My question is all in the context of this paper. I have problems understanding a definition and a method. Sina, C. et al. Mitochondrial gene polymorphism is associated with gut microbial communities in mice. Sci. Rep. 7, 1–9 (2017). This is a segment of the introduction: " Since common inbred...

    Biology Genetics: Mutation and Complementation

    Thank you for answering! That is good to know. I believe we are just making this assumption in the context of my class.

    Biology Genetics: Mutation and Complementation

    Thank you for answering! I wonder what if the Y chromosome carries a recessive gene, and the X chromosome of that same male individual carries a dominant gene, then wouldn't the trait on X chromosome be expressed instead of Y? What about Xdom.Ydom.? Xrec.Ydom.? In the context of my class we...

    Biology Genetics: Mutation and Complementation

    Homework Statement Question 2[/B] You mutagenize male flies with EMS. Next you mate an EMS-treated male fly to a wild-type female fly. (i) If you find an F1 offspring with a sleep-too-little mutant phenotype, what does that suggest to you about this mutation? (ii) You expect that majority of...

    Geometric optics: Thin lense equation

    Is this the correct approach though? I'm not sure what other equation to use

    Geometric optics: Thin lense equation

    Homework Statement A 2.0-cm-tall candle flame is 2.0 m from a wall. You happen to have a lens with a focal length of 32 cm. How many places can you put the lens to form a well-focused image of the candle flame on the wall? For each location, what are the height and orientation of the image...

    Thin-film interference: transmission & reflection of colors

    I think it makes more sense now, thank you!

    Thin-film interference: transmission & reflection of colors

    So most (but not all) yellow light are transmitted (m) , and most violet are reflected (m+ 0.5), while red or green lies somewhere in between (m+0.2 etc)?
