A researcher randomly assigned N = 16 rodents to experience one of four levels of shock (n = 4 per group) following the illumina

tion of a visual cue. If SSBG = 24 and SSE = 48, then what was the decision at a .05 level of significance for a one-way between-subjects ANOVA?

Answer:

The hypothesis should be retained

Step-by-step explanation:

We are given:

N= 16

n = 4

SS_B_G = 24

SS_E = 48

Level of significance, a = 0.05

From the given data, our ANOVA table will be:

----Source: Between---- Residual---

------DF:n-1=> 4-1=3------N-n=>16-4=12

------SS: SS_B_G = 24---- SS_E =48

----MS: MS_B_G = 8----MS_E=48/12=4

Note: proper ANOVA table is attached

The statistic will be written as:

TS = \frac{MS_B_G}{MS_E} ~ F_n_-_1, _N_-_n

T = 8/4 = 2

Therefore

F_n_-_1, _N_-_n, _a

=> F_3,_1_2,_ 0_._0_0_5 = 3.490

The hypothesis should be retained, because we no know that the statistic is in the acceptance area.

What are the domain and range of the function f(x) = x^4-2x^2-4 ?
tatuchka [14]

Answer:

Think about what domain and range is. Domain is the x and range is the y.

Step-by-step explanation: What values of x can you put in this function? Is there any number you cannot use?? Then what y's will you get back? The best way to find out might be to graph it to look. Since it is an even function whose ends go up, all the y's will be greater than or equal to the y value of the vertex.
