- The mean weight of loaves of bread produced at the bakery where you work is supposed to be 1 pound. You are the supervisor of quality control at the bakery, and you are concerned that new employees are producing loaves that are too light. Suppose you weigh an SRS of bread loaves and find that the mean weight is 0.975 pound. What are the appropriate hypotheses for performing this significance test? Ho : x = 1; H. : x < 1 where i = the sample mean weight (in pounds) of bread loaves produced at the bakery. Ho : u = 1; H. : µ < 1 where u = the true mean weight (in pounds) of bread loaves produced at the bakery. Ho : µ < 1; H, : H = 1 where u = the true mean weight (in pounds) of bread loaves produced at the bakery. Ho : u = 1; H. : p = 0.975 where u= the true mean weight (in pounds) of bread loaves produced at the bakery. Ho : u = 1; H. : u # 1 where u= the true mean weight (in pounds) of bread loaves produced at the bakery.arrow_forwardDraw a graph of V0 vs. [S] (Michaelis-Menten plot) for these data.

Normative hair cell data for the lateral semicircular canal in humans. Linear fitted regression line is included (n = 67). The above graph shows... a) a decrease in taste buds with age in humans.b) the relationship between hair cell density and age in humans.c) the complete loss of a photoreceptor in humans 80 years old and above.d) the disappearance of hair follicles in older humans.e) a higher density in a type of mechanoreceptor in younger humans. 2) Figure 1. Normative hair cell data for the lateral semicircular canal in humans. Linear fitted regression line is included (n = 67).

He has collected data and comes up with the linear model T=39.2+0.233r, where T is the temperature in degrees Fahrenheit and r is the number of chirps per minute. Interpret the slope of the equation. The model predicts a decrease of 0.233 degrees for each increase of 1 chirp per minute. The model predicts a decrease of 39.2 degrees for each increase of 1 chirp per minute. The model predicts an increase of 39.2 degrees for each increase of 1 chirp per minute. The model predicts an increase of 0.233 degrees for each increase of 1 chirp per minute.arrow_forward

Compare these values to the values obtained Vmax = 525.3 µM/sec Km = 20.70 µM . Which method, nonlinear regression or linear regression, is more tolerant to an experimental error? Note that lower substrate concentrations, which often have the greater error, have a greater effect on the slope of the line in the Lineweaver-Burk plot.arrow_forwardWhy is it difficult to accurately estimate Km and Vmax values from a Michaelis-Menten plot?
