QUESTION 7 Cerulean City's Nurse Joy claims that the mean number of Pokemon the trainers at Cerulean Gym have is 23. Saffron City's Nurse Joy wants test the claim. A random sample of 21 trainers has a mean number of 20.4 Pokemon. The standard deviation for all trainers is 4.2 Pokemon. At a level of significance of 5%, do you have enough evidence to reject the claim? Assume the population is normally distributed.

A. Find the standardized test statistic. Show work in order to receive credit on this question. Round answer to the hundredths place (2 decimal places).

B. Find the P-value. Explain how you found the value in order to receive credit on this question.

C. Decide whether to reject or fail to reject the null hypothesis. Explain your reasoning to receive credit on this question.

Label your answers as A, B and C.

if farmer matt works for 8 hours a day, how many days will it take him to completely plant 12 rows of crops? each batch of cookies needs 3/4 cups of sugar.

step-by-step explanation:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

236 cm 16 time 12 = 192

6 times 7 = 42

192+42

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
