The u. s. census bureau claims that 26% of all u. s. businesses are owned by women. a researcher in denver believes that the percent is higher there. a consulting firm surveys a random sample of 410 businesses in the denver area and finds that 115 of them have female owners.
what is the p value for testing the hypotheses h0: p=0.26 versus ha: p> 0.26 ? a) 0.946b) 0.172c) 0.344

b) 0.172

Step-by-step explanation:

We have a large sample size n = 410 and .  

For testing the hypotheses vs (upper-tail alternative) the test statistic is given by and the observed value is . The p-value is computed as P(Z > 0.924) = 0.1777 where the random variable Z comes from a standard normal distribution.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
