It is known that roughly 2/3 of all human beings have a dominant right foot or eye. Is there also right-sided dominance in kissing behavior? An article reported that in a random sample of 124 kissing couples, both people in 76 of the couples tended to lean more to the right than to the left. (Use $\alpha$ = 0.05.) USE SALT Does the result of the experiment suggest that the 2/3 figure is implausible for kissing behavior? State the appropriate null and alternative hypotheses. $H_0: P = 2/3$ $H_a: P \leq 2/3$ $H_0: P = 2/3$ $H_a: p < 2/3$ $H_0: p = 2/3$ $H_a: p > 2/3$ $H_0: P = 2/3$ $H_a: p \neq 2/3$ Calculate the test statistic and determine the P-value. (Round your answers to two decimal places and p-value to four decimal places.) z = -1.27 P-value = State the conclusion in the problem context. Reject the null hypothesis. There is not sufficient evidence to conclude that the true proportion of right- leaning behavior differs from 2/3. Do not reject the null hypothesis. There is not sufficient evidence to conclude that the true proportion of right-leaning behavior differs from 2/3. Do not reject the null hypothesis. There is sufficient evidence to conclude that the true proportion of right- leaning behavior differs from 2/3. Reject the null hypothesis. There is sufficient evidence to conclude that the true proportion of right-leaning behavior differs from 2/3.

Which of the following statements are false regarding Python and ChatGPT? Question 19 options: A) If you copy the ChatGPT code for Python into a text editor and save it with a .py extension you can go to the directory where it is saved and in you command line (PC) or terminal (Mac) type py filename,py (PC) or python3 filename,py (Mac) and the code will run. B) Python scripts can be run from the Command Line (PC) or Terminal (Mac). C) Python is open source and therefore free to use. D) PuLP is a Python package that is available to solve non-linear objective functions. E) Many Python packages or libraries are available to accelerate the coding process.

With the aid of appropriate chemical reactions and mechanism appropriate, informatively discuss the destruction of stratospheric ozon
f. The crystal structure of the Gly344 mutant protein is solved and is determined to be nearly identical to the structure of the wild-type protein. The phi-psi angles of the Gly344 mutant protein are plotted in a new Ramachandran plot (not shown here). The combination of phi-psi angles for Gly344 in this structure will: a. be in an "allowed" region for non-glycine residues of the Ramachandran plot b. be essentially the same as for residue Ala344 in the wild-type protein c. be in the a-helical region of the Ramachandran plot d. be in a "disallowed" region for glycine residues in the Ramachandran plot

2. Resolve the force $F_1$ into components along the u and v axes and determine the magnitudes of the components. Hint: apply triangle law/parallelogram law and use law of sines.
12. A triangle is defined by the points A(0, 1, 2), B(1, 0, 2) and C(-1, 2, 0). Find angle A of this triangle.
