A company's quality engineer wants to check whether the average weight of the products coming out of the packaging line does not exceed 10 grams. For this, he measured the weights of the products coming out of the line by making a random selection.The measurement values are presented in the "Product weight of the current state (g)" column in the attached document. After a while, a pressing machine with a newer technology was replaced with a press machine where product losses were frequently experienced in the packaging line. And the products with the same features were weighed after being processed in this new pressing machine. The product weights obtained after the use of the new pressing machine are presented in the column "Product weight after using a new machine (g)". In line with these given, answer the following question using the observation numbers. 1) Using the data set in the column "Product weight of the current state (g)" test whether the average weight of the products…
A certain financial services company uses surveys of adults age 18 and older to determine if personal financial fitness is changing over time. A recent sample of 1,000 adults showed 410 indicating that their financial security was more than fair. Suppose that just a year before, a sample of 700 adults showed 245 indicating that their financial security was more than fair. (a) State the hypotheses that can be used to test for a significant difference between the population proportions for the two years. (Let p1 = population proportion most recently saying financial security more than fair and p2 = population proportion from the year before saying financial security more than fair. Enter != for ≠ as needed.) H0: Ha: (b) Conduct the hypothesis test and compute the p-value. At a 0.05 level of significance, what is your conclusion? Find the value of the test statistic. (Use p1 − p2. Round your answer to two decimal places.) Find the p-value. (Round your answer to…
Approximately 10% of Americans are left-handed (we will treat this as a knownpopulation parameter). A study on the relationship between handedness andprofession found that in a random sample of 105 lawyers, 16 of them were left-handed 1 . Test the hypothesis that the proportion of left-handed lawyers is higher thanthe proportion of left-handed Americans. Use α = 0.01.H 0 : Lawyers are just as likely to be left-handed as other Americans: p = 0.10H 1 : Lawyers are more likely to be left-handed than other Americans: p > 0.10. a. Check to see if the null hypothesis sampling distribution is normal. Keep in mindwhether you are dealing with means or proportions. b. Draw the null hypothesis sampling distribution (a normal curve). Label its center. c. Calculate your test statistic and draw it on your null hypothesis curve. This is justyour sample statistic ( or ) converted to a Z-score on your null hypothesis samplingdistribution. Make sure you are using the appropriate SE formula! Use…

20% of all college students volunteer their time. Is the percentage of college students who are volunteers smaller for students receiving financial aid? Of the 326 randomly selected students who receive financial aid, 46 of them volunteered their time. What can be concluded at the αα = 0.05 level of significance? Z- test for a population proportion The null and alternative hypotheses would be: H0:H0: p = __?__ (please enter a decimal) H1:H1: p is ( choose one <, = or not equal) ____?___ncorr __?__(Please enter a decimal) The test statistic z= __?__(please show your answer to 3 decimal places.) The p-value = __?__(Please show your answer to 4 decimal places.) Thus, the final conclusion is that ... a. The data suggest the population proportion is not significantly lower than 20% at αα = 0.05, so there is insufficient evidence to conclude that the percentage of financial aid recipients who volunteer is lower than 20%. b. The data…
A marriage counselor has traditionally seen that the proportion p of all married couples for whom her communication program can prevent divorce is 79%. After making some recent changes, the marriage counselor now claims that her program can prevent divorce in mot e than 79% of married couples.

An organization believes that the thought of adults ages 55 and over on which industry has the most trustworthy advertising is uniformly distributed. To test this claim, you randomly select 800 adults age 55 and over and ask each which industry has the most trustworthy advertising. The results are shown in the table. At a= 0.05, can you reject the claim that the distribution is uniform (i.e., that each frequency should be the same- in this case, 160, since there are 800 total adults sampled)? Explain.

Two popular drugs used for the treatment of depression are Resithan and Exemor. A random sample of 510 depressed individuals is selected and treated with Resithan, and 187 find relief from their depression. A random sample of 474 depressed individuals is independently selected from the first sample and treated with Exemor, and 152 find relief from their depression. Can we conclude, at the 0.05 level of significance, that the proportion p1 of all depressed individuals taking Resithan who find relief from depression differs from the proportion p2 of all depressed individuals taking Exemor who find relief from depression? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below.

A local gym claims that, if you join today, you will lose at least 20 lbs in 6 months. Below is a sample of 15 individuals who joined the gym 6 months ago. Suppose we weigh these same individuals today to determine the accuracy of the gym's claim. Conduct a hypothesis test to determine if there is evidence to support the claim that the average new member loses at least 20lbs in the 6 months after they first join.

Two popular drugs used for the treatment of depression are Resithan and Exemor. A random sample of 408 depressed individuals is selected and treated with Resithan, and 192 find relief from their depression. A random sample of 520 depressed individuals is independently selected from the first sample and treated with Exemor, and 211 find relief from their depression. Can we conclude, at the 0.05 level of significance, that the proportion p1 of all depressed individuals taking Resithan who find relief from depression is greater than the proportion p2 of all depressed individuals taking Exemor who find relief from depression? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below.
