Geckos are lizards with specialized toe pads that enable them to easily climb all sorts of surfaces. a research team examined th
e adhesive properties of 7 tokay geckos. below are their toe-pad areas (in square centimeters, cm2). 5.6 4.9 6.0 5.1 5.5 5.1 7.5 what is the value of the sample variance? _____ cm2 answer
Step-by-step explanation: Variance is one of the measures of dispersion which is the the second central moment in probability. It is defined as a measure of by how much the values in a data set differs from the mean of the values. Thus it is the average of the squares of the deviations from the mean as this ensures that both the negative and positive deviations do not cancel each other out.
The sample variance would be calculated as follows:
Population size is 7 (5.6 4.9 6.0 5.1 5.5 5.1 7.5)
First you take 29 over 185 and x over 100 and you cross multiply which gives you 185x is equal to 2900 then you take 185x and 2900 and you divide both by 185 and you end up with x equals 15.68 or 15.68% which is letter B
