Estimate of population 0.61
(b) Margin of error = 0.07 The real population interval estimation is ± 7%.
c). Margin of error = 0.15
d) The real population's interval estimation is ± 15%
e). Yes, the action argument of the group is based on a half-range estimation of the true population. The reason that 62% ± 15% = 47%, or 77%, while 47% is similar to 45%, as the Collective action group states. Hope this helps! Mark Brainly please!
Answer:
3.5 ⋅ 10^3
Step-by-step explanation:
As you saw, if two or more fractions have the same denominator, you can compare them by looking at their numerators. As you can see below, 3/4<span> is larger </span>than 1/4<span>. The larger the numerator, the larger the fraction.</span>
