Answer:
Here it is. Hope it helped. Apart from 3, 4 is also a number.
plz mark me as brainliest.
Experimental probability is the outcome during a certain experiment. add up the total number of times it was spinned. You should get 40. To find the experimental probability of each section, simply divide the number by 40. This will give you the percentage for each one. For example, spinner A. 14/40=.35 Multiply this by one hundred to find the percentage (35%). Do this for all and let me know if you need help converting them to fractions. :)
The answer to the question is 1.5
The best way to find fractions that are equal is to find a common factor and divide/multiply them.
So in 25/35 you can easily see that 5 goes into both SO...
25/35 / 5/5 = 5/7
25/35 = 5/7
We are given
<span>μ > 1180
</span><span>α = 0.02
</span><span>σ = 201.71
x = </span><span>1198.79
n = 200
The null hypothesis is </span>μ ≤ 1180 while the alternative hypothesis is μ > 1180
The test statistic is 1.32 which means that the confidence internval is 98%. Getting the z-score
z = (x - μ) / σ
z = (1198.79 - 1180) / 201.71
z = 0.093
For a normally distributed population, the z-score of 0.093 has a p-value of
p = 0.46
