To test the effect of a fertilizer on rice production, 24 equal plots of a certain land are selected. Half of them were treated with fertilizer leaving the rest untreated. Other condition were the same. The mean production of rice on untreated plots was 4.8 quintals with standard deviation of 0.4 quintal. While, the mean yield on the treated plots was 5.1 quital with a standard deviation of 0.36 quintal. Can we say that there is significant improvement in the production rice due to use of fertilizer at 0.05 level of significance? Assume that the variance of population are unknown but not equal.

A single serving bag of Ray's Classic Potato Chips is listed on the package to be 28.3 grams. The manufacturing process for potato chips can vary from bag to bag. The listed weight of the bag of potato chips is the average weight. The weight of a bag of Ray's chips is known to be Normally distributed with a standard deviation of 0.4 grams. Ray's Potato Chips will not sell any bags that are in bottom 4% of all weights. Find the maximum value that would put a randomly selected bag of Ray's chips at the 4th percentile of weights. O a. 27.6 grams O b.27.24 grams O. 28.2 grams O d.29.0 grams
An interested citizen wanted to know if Democratic U. S. senators are older than Republican U.S. senators, on average. On May 26 2013, the mean age of 30 randomly selected Republican Senators was 61 years 247 days old (61.675 years) with a standard deviation of 10.17 years. The mean age of 30 randomly selected Democratic senators was 61 years 257 days old (61.704 years) with a standard deviation of 9.55 years. Do the data indicate that Democratic senators are older than Republican senators, on average? Test at a 5% level of significance. a. At the 5% level of significance, from the sample data, there is NOT sufficient evidence to conclude that the mean age of Democratic senators is greater than the mean age of the Republican senators. b. At the 5% level of significance, from the sample data, there is sufficient evidence to conclude that the mean age of Democratic senators is greater than the mean age of the Republican senators.
The heights of women are normally distributed with a mean of 63.6 inches and a standard deviation of 2.5 inches. (show all work) To be considered extremely tall, a woman’s height must fall in the top 2% for all heights of women. What is the benchmark height for this designation? To be considered extremely short, a woman’s height must fall in the bottom 2% for all heights of women. What is the benchmark height for this designation?
Mr. Karim is the owner of Philips home appliance. Recently Mr. Karim observed a differencein the taka amount of sales between the men and women he employed as sales associates. Asample of 40 days revealed the men sold a mean of Tk.1400 worth of appliance per day. For asample of 50 days, the women sold a mean of Tk1500 worth of appliance per day. Assumethe population standard deviation for men is Tk200 and for women Tk250. At the 0.05significance level, can Mr. Karim conclude that the mean amount sold per day is larger for thewomen?
National Cookie Company produces premium chocolate chip cookies for sale in up-scale food markets. Cookies are sold in 250 gram packages of 10 cookies. Unfortunately, the manufacturing process has some inherent variation. After years of improving the process, National has reduced the standard deviation of the process to 0.6 grams per cookie. In the short term, the variation of 2 the production process is outside National’s control. However, National is able to adjust the mean weight level for each cookie. For various economic reasons, setting the mean level properly is important. If it is too high, then the cookies are heavier than required and National must incur unnecessarily high raw material costs; if the mean level is too low, then the cookies must be sold as thrift. a) Assume that National sets the maximum number of underweight packages at 2.5%. Where should National set the mean weight level per cookie?
To qualify for a medical study, an applicant must have systolic blood pressure in the 60% of the middle range. If the systolic blood pressure is normally distributed with a mean of 120 and a standard deviation of 4, find the upper and lower limits of blood pressure a person must have to qualify for the study.
A blood bank is conducting a study on how much time is required of their patients for blood platelet donations. Based on past records, time spent in the waiting room has a mean of 5 minutes and a standard deviation of 1 minute, time spent with a nurse who reviews patients' medical records and measures their vital signs has a mean of 10 minutes and a standard deviation of 3 minutes, and the actual donation time has a mean of 130 minutes and a standard deviation of 8 minutes. Assuming these three times are independent and can all be modeled using a normal distribution, approximately what proportion of donors finish the entire donation process in under 2.5 hours (150 minutes)? (A) 0.66 (B) 0.72 (C) 0.84 (D) 0.89 (E) 0.99
