I have multiple choice quiz home work as below, just give quic answer :
1. Observation data from 10 samples of mobile phone battery life (hours) after recharge are as follows: 7.7, 7.8, 7.9, 7.1, 7.6, 9.3, 8.6, 7.5, 8.4. Test with a sign test, Ho: the median is not the same as then at the test level of 10%: a. Ho Accepted b. Hi rejected C. Hi Accepted d. Hi accepted at test level 5% 2. If the known T test (t count) is 2.75, then the conclusion that can be drawn from the results of the two-way hypothesis test (two tail test) with the number of samples n = 20, is: a. Reject Ho b. Accepted Ho c. Reject H1 d. Accepted Hz 3. table ANOVA nya diperoleh sebagai berikut ; Source DB JK KT F p-value Regression 1 1432.07 1432.07 22.619 0.01764 residual 3 189.93 Total 4 Based on the ANOVA table above, the value of R3 (multiple R-squared) is: a. 0.8829 b. 0.9396 C. 88.29 4. To test the model and guess the parameters of the model are sampled and recorded as follows: X 1 10 20 30 40 4 10 25 50 The alleged regression line equation is : a. Y=6x-120 b. Y=6X+120 C. Y=2x+40 d. Y=4x+405 . The null hypothesis, (Ho) for the freedom of its form test is . Ho : There is no link between factor A and factor B. b. Ho : There is a link between factor A and factor B. 6. The paired t test contains n pairs of observations (data). What is the degree of freedom for this test? ; a. 2n-1 b. 2n C. n-1 d. n 7 To test whether there is a difference in battery life of AA and BB brands after recharge, observations were made on 8 samples of AA brands and 10 samples of BB brands and obtained data as follows AA brand: 7.7, 7.8, 7.9, 7.1, 7.6, 8.6, 7.5 and 8.4 and bb brands: 7.9, 7.4, 8.6, 8.8, 8.5., 9.4, 8.9, 9.0, 8.2, 8.3. To test whether there is a difference between the two brands, hypothesis testing Ho : 01 = 02 and Hi = 01#02 (01 is not the same as 02) through the Number-Sum test Wilcoxon at the test level 5%, with statistic U. from the data obtained $1 = 36 and $2 = 55, then the statistical values U1 and U2 a. U1=13 dan U2=66 b. U1=49 dan U2=121 c. U1=30 dan U2=61 d. U1=49 dan U2=66 8. A researcher tested the durability of wax as a layer of paint on a car. There are three types of wax to try (typel, type2 and type 3). It is then measured how long the wax layer begins to fade. The real level of a for testing is 0.05, Hypotesis null for this variety analysis is : a. Not all types of wax have the same average durability. b. At least one type of wax has the same average durability. C. H1= M2= 13= 0 d. H1= 2= H3 9. To test whether there is a difference in battery life of AA and BB brands after recharge, observations were made on 8 samples of AA brands and 10 samples of BB brands and obtained data as follows AA brand: 7.7, 7.8, 7.9, 7.1, 7.6, 8.6, 7.5 and 8.4 and bb brands: 7.9, 7.4, 8.6, 8.8, 8.5., 9.4, 8.9, 9.0, 8.2, 8.3. To test whether there is a difference between the two brands, hypothesis testing Ho: 01 = 02 and Hi = 01#02 (01 is not the same as 02) through the number of rank tests (Rank-Sum test) Wilcoxon at the test level 5%, with statisticS U. from the data obtained U1 = 13 and U2 = 66, then the hypothesis : a. Ho accepted because U=17 b. H1 accepted because U>17 C. H1 accepted because U1310. If in the hypothesis test of population variety is known, then what is used as a statistical test is : a. test Z b. Test t C. Test F d. Test xStep by Step Solution
