The Journal de Botanique reported that the mean height of Begonias grown while being treated with a particular nutrient is 45 centimeters. To check whetherthis is still accurate, heights are measured for a random sample of 15 Begonias grown while being treated with the nutrient. The sample mean and samplestandard deviation of those height measurements are 49 centimeters and 11 centimeters, respectively.Assume that the heights of treated Begonias are approximately normally distributed. Based on the sample, can it be concluded that the population mean heightof treated begonias, μ, is different from that reported in the journal? Use the 0.10 level of significance.Perform a two-tailed test. Then complete the parts below.Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.)(a) State the null hypothesis Ho and the alternative hypothesis H₁.HoH₁ :(b) Determine the type of test statistic to use.(Choose one)(c) Find the value of the test statistic.

Solve the problem. When performing a hypothesis test for the ratio of two population variances, the upper critical F value is denoted FR. The lower critical F value, FL, can be found as follows: interchange the degrees of freedom, and then take the reciprocal of the resulting F value found in table A-5. FR can be denoted Fa/2 and FL can be denoted F1-a/2 - Find the critical values FL and FR for a two-tailed hypothesis test based on the following values: n₁ = 4, n₂ = 8, a = 0.05 0.1703, 5.8898 0.1112, 5.0453 0.0684. 5.8898 O 0.1211, 4.3541
