I think you divide 18.96 by 3 to get the amount for one pound cost then go pound for pound there
A = 50% / equally likely
B = less likely / unlikely
C =less likely
D = Impossible
3t-1=8
3t=8+1
3t=9
3t divide by 9
Will give you 3
So your t value would be 3
Explanation: you would have to bring the -1 over to the 8, making the 1 positive. Then you would add up 8 nd 1.
And just divide the two numbers so 9 divide by 3. And you would have your answer T=

The value of alpha is 0.26, assuming a confidence level of 74%.
<h3>What is the margin of error?</h3>
The significance level α is the probability of making the wrong decision when the null hypothesis is true.
Alpha levels which is also called as significance levels are used in hypothesis tests.
Given
When finding the margin of error for the mean of a normally distributed population from a sample.
The confidence interval = 74% = 0.74.
The value of the alpha is given by;
Substitute all the values in the formula
Hence, the value of alpha is 0.26, assuming a confidence level of 74%.
