Over the past several years, the proportion of one-person households has been increasing. the census bureau would like to test the hypothesis that the proportion of one-person households exceeds 0.23. the hypotheses of interest are given below: h0: p ≤ 0.23 ha: p > 0.23 a random sample of 136 households found that 43 consisted of one person. the census bureau would like to set α = 0.05. what is the value of the test statistic for this scenario? round your answer to two decimal places.

z =2.39

Step-by-step explanation:

Given :

A random sample of 136 households found that 43 consisted of one person.

i.e. Sample size : n= 136

Sample proportion :

Test statistic for proportion :-

Hence, the value of the test statistic: z =2.39

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
