It can be deduced that the null hypothesis is H: p = 0.25 and the alternative hypothesis is H: p > 0.25.
<h3>What is the null hypothesis?</h3>
It should be noted that null and alternate hypothesis are written based on the population parameter.
From the information given, the claim is that they card was identified significantly more than chance would suggest. The proportion of card selected will be:
= 1/4 = 0.25
Therefore, the null hypothesis is H: p = 0.25 and the alternative hypothesis is H : p > 0.25.

H would equal to 4 (8+4=12)
Answer:
3300 Ghana cedis
Step-by-step explanation:
There are 2000 items, so n = 2000
P = 3/4 * 2000 + 1800 = 1500 + 1800 = 3300 Ghana cedis
After 28 days she will have 200. every 28 days she saves 80 dollars and after 112 she will have saved 320. She will then be at 460 and need 40 more dollars which is 14 days, and 112 plus 14 is 126 days. Hope that helped
Answer:
The zeros are : 0, 3, -6, 7.
Step-by-step explanation:
Zeros of a polynomial is the values at which the polynomial becomes zero. They are also called the roots of the polynomial.
When (x - a)(x - b) = 0, we can say that either (x - a) = 0 or (x - b) = 0. At least one zero renders the whole equation to be zero.
Now, we are given that: x. (x - 3). (x + 6). (x - 7) = 0
⇒ To make the equation zero, at least one of the following should be true:
x = 0
x - 3 = 0 ⇒ x = 3
x + 6 = 0 ⇒ x = -6
x - 7 = 0 ⇒ x = 7
Therefore, x can take any one of the above values and that would make the polynomial zero.
