2
The kind of test to use is a t -test because a t -test is used to check if there is a difference between means of a population
3
4
The p-value is
5
The conclusion is
There is sufficient evidence to conclude that the mean amount of Walker Crisps eaten was significantly higher for the children who watched the sports celebrity- endorsed Walker Crisps commercial
The test statistics is
Step-by-step explanation:
From the question we are told that
The first sample size is
The first sample mean is
The second sample size is
The second sample size is
The first standard deviation is
The second standard deviation is
The level of significance is
The null hypothesis is
The alternative hypothesis is
Generally the test statistics is mathematically represented as
=>
=>
The p-value is mathematically represented as
Generally from the z table
=>
From the values obtained we see that so the null hypothesis is rejected
Thus the conclusion is
There is sufficient evidence to conclude that the mean amount of Walker Crisps eaten was significantly higher for the children who watched the sports celebrity- endorsed Walker Crisps commercial
Let's solve this problem. We know the equation of <span>the height of the ball that is:
</span>
<span>
Where x represents </span><span>the horizontal distance in yards the ball has traveled in the air. We know that a distance is always positive, so we conclude that x must be greater or equal than 0, so:
</span>
<span>
The horizontal plane represents the zero of the function, given that there is no possibility for the ball to get negative values, then

Answer:
Step-by-step explanation:
Numbers can be arranged in decreasing order (this means that they are ordered from greatest to least) and in increasing order (which means that they are ordered from least to greatest).
In this case, you are asked to arrange the number from least to greatest (increasing order). Then:
The least number is 0.10299 and the greatest is 1.1
Then:
