A biologist is testing to see whether applying organic fartilizer to a complant results in more cars of corn per stalk. An experiment is conducted and data are collected from 40 treated walks and 32 un treated stalk. The treated stak (sample A) produces an average of 2.04 mars of com with a standard deviation of 0.24. The un-treated talks (sample 8) produced an average of 168 ears of corn with a standard deviation of 0.45. Assume that the population variances are equal a state the ruil and alternative hypothesis for the daim that the average number of ears per stark is Higher for the treated stalks HIMANO H, ATM The ve hypothesis is the daim The goal of the testito the claim d. We will tan t-test with degrees of freedom calculate the standardited test statistic for the hypothesis test rounded to 2 decimal place Keep in mind that the form for the denominator depends on whether the test is pooled or unpooled. You can view the two formulasi new tab here Calculate the value of the hypothesis stranded to decimales 0 come to conclusion at the same level Tall to reject the hypothes Sect the poth

9. Come to a conclusion at the 0.05 significance level: O Fail to reject the null hypothesis Reject the null hypothesis h. Interpret your results: There is not enough evidence to refute the daim that the average number of cars per stalk is higher for the treated stalks There is enough evidence to support the claim that the average number of ears per stalk is higher for the treated stalks. There is enough not evidence to support the claim that the average number of ears per stalk is higher for the treated stalks. There is enough evidence to refute the claim that the average number of ears per stalk is higher for the treated stalks
