Student learning outcomes
The student will select the appropriate distributions to use in each case.
The student will conduct hypothesis tests and interpret the results.
Television survey
In a recent survey, it was stated that Americans watch television on average four hours per day. Assume that
σ = 2. Using your class as the sample, conduct a hypothesis test to determine if the average for students at your school is lower.
H
0 : _____________
H
a : _____________
In words, define the random variable. __________ = ______________________
The distribution to use for the test is _______________________.
Determine the test statistic using your data.
Draw a graph and label it appropriately.Shade the actual level of significance.
Graph:
Determine the
p -value.
Do you or do you not reject the null hypothesis? Why?
Write a clear conclusion using a complete sentence.
Language survey
About 42.3% of Californians and 19.6% of all Americans over age five speak a language other than English at home. Using your class as the sample, conduct a hypothesis test to determine if the percent of the students at your school who speak a language other than English at home is different from 42.3%.

Jeans survey
Suppose that young adults own an average of three pairs of jeans. Survey eight people from your class to determine if the average is higher than three. Assume the population is normal.

Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments
_Adnan
But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️

define infection ,prevention and control
Innocent
I think infection prevention and control is the avoidance of all things we do that gives out break of infections and promotion of health practices that promote life
