Answer:
The data speed 1.4Mbps is in the 34th percentile.
Step-by-step explanation:
To find the percentile of a value X in a data set, we divide the number of values lesser than X in the data set by the total number of values in the data set, and then multiply by 100.
In this set
There are 17 values lesser than 1.4
There are 50 values in all.
So
The data speed 1.4Mbps is in the 34th percentile.
Answer:
Being p1 the proportion for people of ages 36-50 and p2 the proportion for people of ages 21-35, the null and alternative hypothesis will be:
Step-by-step explanation:
A hypothesis test on the difference of proportions needs to be performed for this case.
We have two sample proportions and we want to test if the true population proportions differ from each other, usign the information given by the sample statistics.
The claim is that the proportion of people of ages 36-50 who own homes is significantly greater than the proportin of people age 21-35 who own homes.
The term "higher" will define the alternative hypothesis, that is the hypothesis that represents what is claimed. The null hypothesis always include the equal sign, and will state that both proportions do not differ.
Being p1 the proportion for people of ages 36-50 and p2 the proportion for people of ages 21-35, the null and alternative hypothesis will be:
