... is to compare the means of these different groups. In the cup-a-soup example, we may be interested if the average volume of soup differs between the four lanes. In a study of the strength of ceramic material (bonded Si nitrate), the goal was to determine what factors influenced the strength of the c ...

... From the confidence interval results we know that with 95% assurance the slope is in the range [-0.243,-0.029], in particular at least with 95% assurance the slope is negative. Comment: Even though the R-square is relatively small, this only casts doubt on the predicted values of slope and intercept ...

... using this information, we were able to find the 10th number. What if we were given n – 2 numbers? Pretend that we have exactly the same information as before, but we don’t know the value of the 9th number (let’s call it y). We can try to do the same calculations to solve for the missing values: 75. ...
