Using a wheatstone bridge, solve for Vout for quarter, half, and full bridges and determine which one is most sensitive. Draw a diagram showing how you would place your strain gauges on a beam for each configuration. Discuss how you should use the right kind of strain gauge with appropriate G values to maximize the sensitivity.

Which of the following statements is NOT an explanation for how oxygen is released from oxy-haemoglobin.

Select one:

A.
Carbon dioxide has a stronger affinity than oxygen to heme, and displaces oxygen in tissues.

B.
Formation of carbonic acid lowers the oxygen affinity of haemoglobin in tissues.

C.
The structure of deoxyhemoglobin is stabilized by the interaction with BPG.

D.
Salt bridges are formed with N-terminal carbamates in deoxyhemoglobin.

E.
Salt bridges are formed between acidic and basic side chains of His146 and Asp94, respectively in deoxyhemoglobin .

4.

Which of the following description of hemoglobin S (HbS) forming fibrous aggregates is FALSE?

Select one:

A.
Valine at position 6 of the β chains form hydrophobic interaction with other HbS.

B.
Formation of aggregates occurs more severely in homozygotes, i.e. both alleles carrying the mutation.

C.
The aggregates distort the shape of the red blood cells.

D.
Formation of aggregates occurs only in deoxygenated form of HbS.

E.
More aggregates are formed in lungs.

Nina is looking to analyze the distribution of the variable X=’grading. She gathered information from 1900 to 2000, and her data concludes X follows a normal distribution with mean 75 and variance 30.

1. What is the probability that a typical student from the current cohort enrolled receive a grade above 80?
2. Between what values will the grades of the 95% of all students in the current cohort fall?
3. Find the value that represents the 25^th and 75^th percentile of this distribution. Then, find the interquartile range. Can a student who got 45 be considered a potential outlier, explain the reasoning.

PLEASE SHOW EACH STEP AND EXPLAIN EACH STEP AS TO WHERE YOU ARE GETTING VALUES FROM (i.e., if you got value from z table, tell me why you use that table and where exactly). use mathematical formula as well as give me a reason why you used what formula you used.

The Cambridge Study of delinquent development was undertaken in N. London to investigate the links between criminal behavior in young men and socioeconomic factors of the upbringing. A cohort of 395 boys was followed for about 20 years starting at the age of 8 or 9. All boys attended 6 schools located near the research office.

The table below provides the following summary statistics relating family income and convictions.

Income level

• Can we consider the cohort of these boys to be a random sample of a certain portion of the male youth of UK?
• What is the necessary assumption that needs to be made about the income group assignment of these boys for the duration of the study?
• Identify the random variables of the data set. What is the type of these variables?
• Construct the appropriate plot of these data.
• Do the two random variables seem to have an association? Which one can be used as explanatory?

Create a PHP class named "User" with the following private fields:

name,

birthdate in yyyy/mm/dd format,

age, and

department.

In the class, include getter and setter methods to get and set the values of those variables.

Author a data entry webform using HTML text input boxes and a submit button. When the user clicks on the submit button, a "User" class is instantiated and the new User object's fields are populated. The HTML input boxes correspond to the field in the "User" class.

Add an "Insert" button that allows the user to insert the form data to a MySQL table.

Add a "Display" button the displays the contents of your MySQL table on the web form when the end-user clicks on the button.

Describe why a coastal location, like Santa Monica or San Diego, has a more moderate climate throughout the year than an inland location like Little Rock, AR or Dallas, TX? Provide 4 main reasons.

1. Suppose a random sample of 500 adults from Santa Clara County answered this question: “in general, do you believe in ghosts?” 225 responded that they believe in ghosts. Test whether it is plausible that, if you could ask all adults in the Santa Clara County this question, less than half would say they believe in ghosts. Use the significance level of 0.01 for this test. Do not forget to follow those five steps.

2. Suppose you believe that your long-time supplier of face masks produced less than 2% defective face masks.
