The statistical significance of 10 winners who bought all their lottery tickets in the same store.

Question

A drink filling machine, when in perfect adjustment, fills the bottles with 8 ounces of drink on an average. Any overfilling or underfilling results in the shutdown and readjustment of the machine. A sample of 20 bottles is selected, and the sample shows an average filling volume of 7.5 ounces. To determine whether the machine is properly adjusted, the correct set of hypotheses Ho: [Select] [Select] H₁: [Select] [Select] > [Select] [Select]

Answer 1

Question

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.

Information on a packet of seeds claims that 93% of them will germinate. Of the 200 seeds that were planted, only 180 germinated. 95% confidence interval for the true proportion of seeds that germinate based on this sample is (85.8%, 94.2%). Do the data provide evidence against the claim? [Select] The margin of error in the estimate is: [Select] > To keep the margin of error within 3.5% with at least 95% confidence level, the required sample size is: [Select]
