The test statistic of zequals2.31is obtained when testing the claim that pgreater than0.9.a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of alphaequals0.10,should we reject Upper H 0or should we fail to reject Upper H 0?

Step-by-step explanation:

a) From the information given, we can state the hypothesis as follows:

For null hypothesis,

p = 0.9

Or

p ≤ 0.9

For alternative hypothesis,

p > 0.9

Because of the greater than inequality symbol in the alternative hypothesis, it means that it is a right tailed test.

b) Since z = 2.31, we would determine the p value by looking at the probability corresponding to the area above the z score from the normal distribution table. Thus

P value = 1 - 0.9896 = 0.0104

Using a significance level of alpha equals 0.10, since alpha, 0.10 is > p value, 0.0104, then we would reject the null hypothesis.

i can you with this question sweetie!

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
