According to a guide, 47% of cell phone users have only one cell number, 31% have two numbers, 8% have three numbers, and 14% have four or more numbers. An independent survey of 935 randomly selected cell phone users found that 464 pay for only one number, 331 pay for two numbers, 113 pay for three numbers, and 27 pay for four or more numbers. Conduct a test to determine if the data from the independent survey contradict the percentages reported by the guide. Use a = 0.01. Determine the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: P1 = P2 = P3 = P4 Hạ: P1 # P2 # P3 # P4 O B. Ho: P1 # P2 # P3 # P4 Ha: At least one of the multinomial probabilities equals its hypothesized value. С. Но: ра 347%, рә %3D 31%, р3 3 8%, ра 3 14% Ha: At least one of the multinomial probabilities does not equal its hypothesized value. Now find the test statistic. x² = |(Round to two decimal places as needed.)

Quadratic Equation

When it comes to the concept of polynomial equations, quadratic equations can be said to be a special case. What does solving a quadratic equation mean? We will understand the quadratics and their types once we are familiar with the polynomial equations and their types.

Demand and Supply Function

The concept of demand and supply is important for various factors. One of them is studying and evaluating the condition of an economy within a given period of time. The analysis or evaluation of the demand side factors are important for the suppliers to understand the consumer behavior. The evaluation of supply side factors is important for the consumers in order to understand that what kind of combination of goods or what kind of goods and services he or she should consume in order to maximize his utility and minimize the cost. Therefore, in microeconomics both of these concepts are extremely important in order to have an idea that what exactly is going on in the economy.
