What does t-value>2 mean?
| The measured value and the actual (known) value is in good agreement |
| The discrepancy between the measured value and the actual (known) is one standard deviation |
| The measured value and the actual (known) value is not in good agreement |
| The discrepancy between the measured value and the actual (known) is less than one standard deviation |
Homework Answers
Ans: the t-statistic measures how many standard errors the coefficient is away from zero. Generally, any t-value greater than +2 or less than – 2 is acceptable. The higher the t-value, the greater the confidence we have in the coefficient as a predictor. Low t-values are indications of low reliability of the predictive power of that coefficient.
So ,here we can say The measured value and the actual (known) value is in good agreement

2. Consider a process in which the applied measured load has a known true mean of 100 N with variance of 400 N. What is the probability that this sample will have a mean value; i. less than 90? II. greater 110? iii. between 90 and 110? Recall that the Standard Deviation is the square root of Variance.

The mean serum-creatinine level measured in 12 patients 24 hours after they received a newly proposed antibiotic was 1.2 mg/dL. 1. If the mean and standard deviation of serum creatinine in the general population are 1.0 and 0.4 mg/dL, respectively, then, using a significance level of 0.05, test whether the mean serum-cre level in this group is different from that of the general population. 2. What is the p-value for the test? 3. Suppose t1.52 and a on one-sample t...

Customer satisfaction is measured on a scale between -2 and 2. The last survey estimated mean customer satisfaction to be .53 with a known standard deviation of 3.64. Another survey is going to be taken. Given past results, you really need to have a margin of error of .18 in your 95% confidence interval. What is the smallest sample size that will get you this margin of error?
