The fоllоwing infоrmаtion pertаins to Questions 15 - 25.  A MMIC low noise аmplifier module has a gain of 13 dB,  noise figure of 1.9 dB, a noise equivalent bandwidth of 500 MHz, input-referred 1 dB compression point of -1 dBm, and input-referred IP3 of 11 dBm. What is the equivalent noise temperature for the module?  Express your answer in kelvin to one place after the decimal.

Questiоn 4 Using the sаme Lоw birthweight dаtаset, run a full linear regressiоn model to determine if lwt (mother’s weight at last menstrual period) and age (age of the mothers) are associated with the birth weight (bwt – dependent variable) of the children in the sample. In your final model, interpret what the values of the following measures, indicate; 4.1. What does the model’s p-value (Prob > F) of 0.027 indicate? A - it indicates that the model is statistically significant and that the dependent variables are aligned with the independent variables B - it indicates that the model is well specified and that the independent variables reliably predict the dependent variable C -it indicates that the model is not well specified and that the independent variables reliably predict the dependent variable D - it indicates that the model is not statistically significant and that the dependent variables are aligned with the independent variables Type the correct answer here [BLANK-1] 4.2. True or False, the model's adjusted R-squared value of 0.02 (2%) indicates that the model is variance explained by the independent variables is statistically significant Type the correct letter here [BLANK-2] (Do not write the entire statement, just the corresponding letter) 4.3.The regression coefficient for the ages of the mothers is [BLANK-3] and that of the mother's weight at the last menstrual period is [BLANK-4] (write the entire number as is. Do not round off) 4.4. Which of the following statements below provides the correct interpretation for regression coefficient of the mother's age and the children's weight? A - 7.9 kilogram increase in weight is associated with the mother's age, however this association is not statistically significant (p=0.429) B - one year increase in age is associated with 7.9 grams increase in the body weight of the children, however this association is not statistically significant. C - one year increase in age is associated with 7.9 grams increase in the body weight of the children,and this association is statistically significant. D - 7.9 kilogram increase in weight is associated with the mother's age, and this association is statistically significant (p=0.429) Write the correct LETTER here [BLANK-5] 4.5. Perform an appropriate test to check multicollinearity in your independent variables. Does the data show any evidence of multicollinearity?  Yes/No [BLANK-6]
