Suppose a random sample of 100 observations from a binomial population gives a value of ModifyingAbove p with caretequals0.76 and you wish to test the null hypothesis that the population parameter p is equal to 0.70 against the alternative hypothesis that p is greater than 0.70.

a) nothing that p = .63, what does your intuition tell you? does the value of p appear to contradict the null hypothesis?

b) use the large-sample z-test to test H0: p = .70 against the alternative hypothesis, Ha: p < 70. Use a = .05. How do the test results compare with your intuitive decision from part A?

c) find and interpret the observed significance level of the test you conducted in part B.

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

hello umm i don't understand your question can you explain it more pls

step-by-step explanation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
