The student will select the appropriate distributions to use in each case.
The student will conduct hypothesis tests and interpret the results.
Supplies:
The business section from two consecutive days’ newspapers
3 small packages of M&Ms®
5 small packages of Reese's Pieces®
Increasing stocks survey
Look at yesterday’s newspaper business section. Conduct a hypothesis test to determine if
the proportion of New York Stock Exchange (NYSE) stocks that increased is greater than theproportion of NASDAQ stocks that increased. As randomly as possible, choose 40 NYSE
stocks and 32 NASDAQ stocks and complete the following statements.
In words, define the Random Variable. ____________=
The distribution to use for the test is:
Calculate the test statistic using your data.
Draw a graph and label it appropriately. Shade the actual level of significance.
Graph:
Calculate the p-value:
Do you reject or not reject the null hypothesis? Why?
Write a clear conclusion using a complete sentence.
Decreasing stocks survey
Randomly pick 8 stocks from the newspaper. Using two consecutive days’ business
sections, test whether the stocks went down, on average, for the second day.
In words, define the Random Variable. ____________=

Do you reject or not reject the null hypothesis? Why?
Write a clear conclusion using a complete sentence.
Candy survey
Buy three small packages of M&Ms and 5 small packages of Reese's Pieces (same net weight as the M&Ms). Test whether or not the mean number of candy pieces per package is the same for the two brands.

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 ❣️

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
