The normal pulse rates for healthy adults are ranging from 60 to 100 beats per minute (bpm).The pulse rates for 20 males and 20 females from the same population are collected. Themeans and standard deviations of the two samples are as follows: (Use 5% significant level.)a)Males: ž = 80 bpm; s1 = 12 bpm;Females: i, = 75 bpm; s2 = 10 bpm;(i)Find the point estimates for the population mean and standard deviation.(ii)How large is the sample sizes needed if the maximum margin of error of the estimatemust be within 2 bpm?Is there any evidence to conclude that the distribution of the pulse rates of the malesand females are different?(iii)

Given information: Males: x¯1=80 bpm; s1=12 bpmFemales: x¯2=75 bpm; s1=10 bpm

Answered: The normal pulse rates for healthy…

A population has a mean u = 90 and a standard deviation o = 30. Find the mean and standard deviation of a sampling distribution of sample means with sample size n= 231. H = (Simplify your answer.)
a survey is conducted to compare the proportions of men and women whoaccess their bank statements online. Denoting the population propotions by Pm and Pw, a two-proportion z-test is carried out to test Ho: pm = pw against Ha: pm > pw. The values of the test statistic is found to be z = 0.784, and the p-value for the test is found to be 0.216. Which of the following is the correct interpretation of the p-value? a) given that ha is true, the probability of getting a value of z at least as large as 0.784 is 0.216. b) given that ho is true, the probability of getting a value of z at least as large as 0.784 is 0.216. c) given the results of the survey, the probability that Pm > Pw is 0.216. d) given the results of the survey, the probability that Pm = Pw is 0.216. e) none of the above

Because the mean is very sensitive to extreme values, it is not a resistant measure of center. By deleting some low values and high values, the trimmed mean is more resistant. To find the 10% trimmed mean for a data set, first arrange the data in order, then delete the bottom 10% of the values and delete the top 10% of the values, then calculate the mean of the remaining values. Use axial loads (pounds) of aluminum cans listed below for cans that are 0.0111 in. thick. Identify any outliers, then compare the median, mean, 10% trimmed mean, and 20% trimmed mean. 247 261 269 273 275 280 282 282 284 285 285 287 290 292 293 296 296 299 311 507 Identify any outliers.

On an intelligence test, the mean number of raw items correct is 236 and the standard deviation is 39. What are the raw (actual) scores on the test for people with IQs of (a) 119, (b) 81, and (c)100? To do this problem, first figure the Z score for the particular IQ score; then use that Z score to find the raw score. Note that IQ scores have a mean of 100 and a standard deviation of 15. (a) What is the raw (actual) score on the test for people with an IQ of 119?
The city of Oakville has 60000 households. A social researcher from the University of Toronto collected a simple random sample of 100 households. Let the auxiliary variable x be the number of persons living in the household and y be the weekly spending for food. The researcher obtained the following sample statistics: 100 100 2 X; = 320 yi = 10000 E09 x? = 1250 100 E09 y? = 1100000 E00 x;y; = 36000 Ty = 150000 Sx = 1.5 Sy = 31.8 (a) Using the ratio estimation, estimate the mean weekly spending for food and place a bound on the error of estimation. You need to report the numerical values. Show all the steps. Circle the final answer. (b) Using the regression estimation, estimate the total weekly spending for food and place a bound on the error of estimation. You need to report the numerical values. USE MSE = 5200. Show all the steps. Circle the final answer.
