In regression, the difference between the confidence interval and prediction interval formulas is ________.**Multiple Choice**- O the prediction interval is the square root of the confidence interval- O the addition of 1 to the quantity under the radical sign- O no difference- O the prediction interval uses \( p^2 \) and the confidence interval uses \( r \)

Solution A prediction interval is used to predict the estimated value of a single variable only but…

Question Help Give Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 37 passengers, and a flight has fuel and baggage that allows for a total passenger load of 5,994 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be Meal 5,994 lb Stan overloaded if the mean weight of the passengers is greater than = 162 Ib. What is the probability that the aircraft is overloaded? Should the pilot take any 37 action to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 174 lb and a standard deviation of 37.1. Righ The probability is approximately (Round to four decimal places as needed.)
We wish to estimate what percent of adult residents in a certain county are parents. Out of 400 adult residents sampled, 24 had kids. Based on this, construct a 90% confidence interval for the proportion p of adult residents who are parents in this county.Express your answer in tri-inequality form.

To test for any significant difference in the number of hours between breakdowns for four machines, the following data were obtained. Machine Machine Machine Machine 1 2. 3 4 6.7 9.0 10.9 9.8 8.1 7.5 10.2 12.5 5.6 9.7 9.4 11.8 7.7 10.3 10.1 10.6 8.6 9.4 9.1 11.2 7.7 9.9 8.5 11.3 (a) At the a = 0.05 level of significance, what is the difference, if any, in the population mean times among the four machines? State the null and alternative hypotheses. O Ho: H1 = H2 = H3 = H4 H: Not all the population means are equal. O Ho: At least two of the population means are equal. H.: At least two of the population means are different. O Ho: H1 = H2 = H3 = H4 O Ho: Not all the population means are equal.

Mean IQ of Attorneys See the preceding excercie, in which we can assume that for the IQ scores. Attorneys are a group with IQ scores that very less that IQ scores of the general population. find the sample size needed to estimate the mean IQ of attorneys, given that we want 98% confidence that the sample mean is within 3 IQ points of the population mean. Does the sample size appear to be practical?
