Arandom sample of 10 of the 2005 nextel cup nascar drivers produced the following ages: 33, 48, 41, 29, 40, 48, 44, 42, 49, 28. a. find the mean age for the 10 nascar drivers of the 2005 nextel cup. b. find the median age for the 10 nascar drivers of the 2005 nextel cup. c. find the midrange of age for the 10 nascar drivers of the 2005 nextel cup. d. find the mode, if one exists, for age for the 10 nascar drivers of the 2005 nextel cup.

Explanation:

Arrange the given data in increasing order

Given, 33, 48, 41, 29, 40, 48, 44, 42, 49, 28.

⇒28,29,33,40,41,42,44,48,48,49

⇒number of sample ,n, =10

⇒The mean is sum of sample÷number of samples

⇒Median is the center value in the data set

28,29,33,40,41,42,44,48,48,49---------In this case , median is half sum of 41 and 42

⇒The mid-range is the mean of the sum of the least and greatest value

=(28+49)÷2 =77÷2=38.5

⇒Mode is the value that appears most in the data set

28,29,33,40,41,42,44,48,48,49-----------mode is 48

e) none of the above answers are correct

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
