<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:
is the required polynomial function of the form
Step-by-step explanation:
The given zeroes of the polynomial is -5 and 4i.
It implies, the roots of the polynomial is (x+5) and (x-4i)
Now, The Polynomial = Product of all its roots
So, here P(x) = ( x + 5)( x - 4i)
or,
⇒
Hence, P(x) is the required polynomial function of the form
