math - Estimate the rate of height growth of humans in km/ hr? -

-

someone asked me question during interview. how go this? not random bs question has math behind it. profile analytic position wanted math skills. couldn't figure out way of calculating this.

here data collected after interview might helpful:

height growth depends on genetic factors, diet, standard of life etc. human grow rate fastest @ birth rapidly declining between 0 & 2, tapering declining rate & rapid rise @ puberty 13 gives second maxima followed steady decline 0 @ age 18.

you may use data or make own assumptions answer question. how go answering based on title of question, knowing need demonstrate strong math skills?

the units red herring: km/hr misleading when we're talking that's more meaningful , intuitive @ cm/year.

with said, you've cited maximum rates between 0 , 2 years old , "puberty". have agree on you're looking for: maximum value or overall value?

since interview question, have state assumptions , give result.

if individual reaches full adult height age 21 years, , average height male in united states 69.2 inches, average growth rate between 3-4 inches per year. since 1 inches = 2.54 × 10-5 kilometers, can see it's 7.5e-5 10e-5 km/year. since 1 year = 8 765.8 hours, i'll leave final multiplication you.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
