- 3.USING GRAPHPAD PRISM: The transformation rate you observed in a treated group of 1036 yeast colonies is 0.193%, while the rate among 1441 untreated colonies is 0.555 %, is there an effect of treatment on transformation? Determine the p-value. SHOW YOUR WORkThe durability of a plastic product is directly affected by the hardness of the plastic types used. Plastic hardness which is measured with the Durometer Hardness test goes between 0 and 100. A higher number represents a harder plastic. A comparative test is conducted to investigate the quality of the plastic based on their hardness from 3 different factory sources. The test is conducted with 6 different plastic types acquired from each factory source. The types of plastic are sorted based on the nature of hardness in ascending order.distribution of candidates who were enrolled for the mba entrace exam and the candidates (out of those enrolled) who passed the exam in different institutes CANDIDATES ENROLLED =8550 X-16%, P- 22%, Q-15%, R-10%, S-17%, T-8%, V-12% CANDIDATES PASSED= 5700 X- 12%, P-18%, Q-17%, R-13%, S-16%, T-9%, V-15% a) What is the percentage of candidates passed to the candidates enrolled for institutes Q and Rtogether?b) What is the ratio of candidates passed to the candidates enrolled from institute P?c)What makes the candidate fail the exam?

- Cumulative information can be portrayed using a graph called an ogive . To construct an ogive, we first make a table that displays cumulative frequencies and cumulative relative frequencies. A cumulative frequency is obtained by summing the frequencies of all classes representing values less than a specified lower class limit (or cutpoint). A cumulative relative frequency is found by dividing the corresponding cumulative frequency by the total number of observations. From the cumulative frequency a graph called ogive can be constructed in this manner: In an ogive, a point is plotted above each lower class limit (or cutpoint) at a height equal to the cumulative relative frequency. Then the points are connected with lines Find the cumulative frequency and relative cumulative frequency and construct the Ogive for each of the following cases: Days to maturity of 40 investments Residential Energy Consumption Survey: Consumption and Expenditures example aboveYour hypothesis test for a proportion has a right-tailed critical region. The test statistic is zz = 1.84.

From the U.S. Census Bureau, in the document International Data Base, we obtained data on the total fertility rates for women in various countries. Those data are presented on the WeissStats site. The total fertility rate gives the average number of children that would be born if all women in a given country lived to the end of their childbearing years and, at each year of age, they experienced the birth rates occurring in the specified year. Use the technology of your choice to decide whether total fertility rates for countries appear to be approximately normally distributed. Explain your answer.
