Answer:
when the advertiser failed to reject the null hypothesis it means that the belief of the newsletter publisher that ess than 26% of their readers own a Rolls Royce is not supported by statistical evidence at 10% significance level.
Step-by-step explanation:
given that a newsletter publisher believes that less than 26% of their readers own a Rolls Royce.
For marketing purposes, a potential advertiser wants to confirm this claim.
After performing a test at the 0.10 level of significance, the advertiser failed to reject the null hypothesis.
For this the hypotheses would be
H0: p = 0.26
Ha: p <0.26
when the advertiser failed to reject the null hypothesis it means that the belief of the newsletter publisher that ess than 26% of their readers own a Rolls Royce is not supported by statistical evidence at 10% significance level.
The scale best estimates to 184, b. Mark me brainliest !!
Answer:
<em>There's an infinite number of possible answers because there might be any multiplication of 3 for boys and any multiplication of 2 for girls. So, for example:</em>
<em>There might be 3 boys and 2 girls.</em>
<em>There might be 6 boys and 4 girls.</em>
<em>There might be 9 boys and 6 girls.</em>
<em>There might be 12 boys and 8 girls.</em>
<em>etc...</em>
<em>In each case the ratio stays the same - 3 : 2.</em>
<em>Of course there probably can't be more than a few dozens of people in one class, but theoretically we can raise the numbers up to infinite.</em>
Step-by-step explanation:<em>hope this help.</em>
Remove the unnecessary parentheses so it would be -1.3x - 4.5 + 2.1x -3.6. combine the like terms -1.3x & + 2.1x & it becomes 0.8x & then you combine -4.5 -3.6 & it becomes -8.1 so your answer is 0.8x-8.1 !! let me know if that was right
