<h2>
Answer with explanation:</h2>
Given : Sample size 
Sample mean : 
Sample standard deviation : 
Let
be the population mean of "like" ratings of male dates made by the female dates.
As per question ,
Null hypothesis : 
Alternative hypothesis :
, It means the test is a one-tailed t-test. ( we use t-test when population standard deviation is unknown.)
Test statistic:

For 0.05 significance and df =188 (df=n-1) p-value = .001582. [By t-table]
Since .001582< 0.05
Decision: p-value < significance level , that means there is statistical significance, so we reject the null hypothesis.
Conclusion : We support the claim at 5% significance that t the population mean of such ratings is less than 8.00.
Answer:
B
Step-by-step explanation:
20 × 30 = 600
30 × 6 = 180
5 × 6 = 30
but 20 × 5 doesn't equal 10
So the maximum x and maximum y is consists the first formula (smaller than or equals 11) u can easily determine the maximum and minimum numbers of variables from given disequilibriums.
