Marisa took a survey and discovered that 38 out of 152 students in the seventh grade at her school have more than one pet. What

mamaluj [8]

Answer:

Step-by-step explanation:

Total number of student in the school = 152 students

Number of student that have more than one pet = 38

percentage of the students have more than one pet will be expressed as

% of student with more than 1 pet = number of student with more than one pet/total number of student * 100%

% of student with more than 1 pet = 38/152 * 100

% of student with more than 1 pet = 3800/152

% of student with more than 1 pet = 25%

Hence 25% of the students in the school have more than one pet.

Answer:

1.28

Step-by-step explanation:

Given that a sample of 1500 computer chips revealed that 55% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 53% of the chips do not fail in the first 1000 hours of their use.

$H_0: p = 0.53\\\\H_a: p \neq 0.53$

(Two tailed test for testing sample proportion with population proportion)

Std error of proportion assuming p = 0.53 is

$\sqrt{0.53*0.47/1000} \\=0.0157$

p difference = 0.02

Z= test statistic = p diff/std error = 1.2775~1.28
