interval dependent variable

There is a linear relationship between the dependent variable and the independent variables. This is called the ________ assumption. The independent variables are not correlated. This is called the _______ assumption. => nonmulticolinearity, linearity or line..

Consider an example. A person was asked to measure the thickness of a coin. He recorded the following readings: (i) 0.2 cm with ruler (ii) 0.23 cm with vernier (iii) 0.231 cm with micrometer The accuracy of thickness of the coin depended on the instrument used for measuring the thickness..

The amount spent by Chris on a birthday party is a function of number of his friends whom he invited. Which of the following is a dependent variable? => Chris′s age or number of members in Chris′s family or number of friends Chris invited or amount spent by Chris on ..

random variables which can assume any value over an interval..

By the study of electronic configuration of transition metals it is understood that variable oxidation state can be formed as there are both ns and (n-1)d electrons in bonding. The participation of ns electrons in bonding leads to +2 oxidation state which is a lower oxidation state. The ..

If the change in velocity in equal intervals of time is not the same, then the object is said to be moving with variable acceleratio..

Let X be continuous random variable which can assume values in the interval [a,b]. A function f(x) on [a,b] is called the probability density function if ..

In a random sample of 25 trees, the variance in height was found to be 6.9. Find the 95% confidence interval for the standard deviation. Assume that the variable is normally distributed. => between 4.9 and 13.7 or between 4.2 and 13.4 or between 5.5 and 14.1 or between 5.5 and 1..

The previous example does hold good only if we ignore the friction or resistance offered by the surface. The distance covered varies with time. For example, a rubber ball dropped from a height, on reaching the ground bounces off to a height less than the initial height and slowly the height decreas..

Find the 95% confidence interval for the variance of the ages of players in a basketball team if a sample of 12 players has a standard deviation of 2 years. Assume the variable is normally distributed. => between 2 and 10 or between 2 and 13 or between 2 and 14 or between 2 and ..
