30. If the level of significance is 0.05 and the p-value is 0.04, what conclusion can you draw?

Inessa [10]

Answer:

Reject null hypothesis

Step-by-step explanation:

Because our p-value of 0.04 is less than the level of significance of 0.05, then we reject the null hypothesis that there's no difference between the means and conclude that a significant difference does exist

liberstina [14]

Answer:

Step-by-step explanation:

1/2 is 3 times 1/6, because 3/1 $\frac{3}{1} * \frac{1}{6} = \frac{3}{6}$ and 3/6 is the same as 1/2. Thus, he can make 3 bowls of granola.

A box holds 8 red and 4 blue beads. Three beads are taken from the box and not replaced. Determine: The probability that all thr

zubka84 [21]

Answer: $\dfrac{14}{55}, \dfrac{13}{55}$

Step-by-step explanation:

Given

There are 8 red and 4 blue beads

Three beads were taken from the box

(i)No of ways of choosing three red beads out of 12 beads is $^8C_3$

Total no of ways $^{12}C_3$

Probability is

$P=\dfrac{^8C_3}{^{12}C_3}=\dfrac{8\times 7\times 6}{12\times 11\times 10}=\dfrac{2\times 7}{11\times 5}\\P=\dfrac{14}{55}$

(ii)atleast two beads refers to minimum two beads

There can be two possibilities (2B,1 R), (3B, 0R)

$\Rightarrow P=\dfrac{^4C_2\times ^8C_1}{^{12}C_3}+\dfrac{^4C_3}{^{12}C_3}\\\\\Rightarrow P=\dfrac{6\times 8}{220}+\dfrac{4}{220}=\dfrac{52}{220}\\\\\Rightarrow P=\dfrac{13}{55}$
