The Food Marketing Institute shows that 50% of households spend more than $100 per week on groceries. Assume the populatic proportion is p = 0.5 and a simple random sample of 100 households will be selected from the population. 1. What is the expectation of Sample Proportion? (to 1 decimals) 2. What is the standard deviation of Sample Proportion? 3. What is the probability that the sample proportion will be within 0.49 to 0.51? Consider a sample of 2500 households selected from the population. 4. What is the expectation of Sample Proportion? 5. What is the standard deviation of Sample Proportion? (to 2 decimals) (to 1 decimals) 6. What is the probability that the sample proportion will be within 0.49 to 0.51? (to 2 decimals) (to 4 decimals) (to 4 decimals)
