any help appreciated! especially checking with what i already have for sig figs!
(2) Calculate the approximate random error ∆h = (1/2) [h(max) - h(min)], where h(max) and h(min) are the highest and lowest values of h. ∆h refers to the random error in each measurement of h.
(3) Calculate the average h_{av} = (1/8)[h_{1} + h_{2} +…+ h_{8}] and the error in the average ∆h_{av} = ∆h/√8, of the eight trials. ∆h_{av} gives an overall estimate for the random error in the eight repeated measurements of h.
(4) Write down your value of h_{av} ± ∆h_{av} according to the rules of significant figures.
(7) What is the range of reaction times from the Class Results table?
(8) Using the measurements listed on the table, calculate the average human reaction time and the error in that average
2. dh = 0.5(hmax - hmin) = 0.6 cm
3. hav = dh/sqrt(8) = 0.21 cm
4. hav + dhav = 0.6 +- 0.21 cm
7. range for t = 0.107 - 0.207 s
8. from the given data
0.191 0.0016
0.178 0.006
0.13 0.02
0.162 0.013
0.19 0.006
0.178 0.004
0.139 0.002
0.125 0.01
0.14 0.007
0.132 0.008
0.139 0.004
0.173 0.005
0.115 0.008
0.122 0.008
0.175 0.004
0.183 0.005
0.16 0.003

0.157 0.002
0.129 0.003
tav = 0.15265 = (t1 + t2 .. tn)/n
n = 20
tmax = 0.191
tmin = 0.115
dt = 0.5[tmax - tmin] = 0.038
dtav = dt/sqrt(n) = 0.008497
hence reaction time = 0.038 +- 0.00-8497
