A score that is 2 points higher than the sample mean has a z-score of z = 0.5 and a score of X = 44 has a z-score of -1.00What is the sample mean?
The research examining the effects of preschool childcare has found that children who spent time in daycare perform better on math and language tests than children who stay home with their mothers. The results show that a sample of n = 25 children who attended daycare before starting school had an average score of M = 87 with SS = 1536 on a standardized math test for which the population mean is μ = 81. The population distribution is normal. Use α= .01 a. Is this sample sufficient to conclude that the children with a history of preschool daycare are significantly better from the general population? b. Compute the 95% confidence interval. show all work

The weights of radish seeds are normally distributed, with µ = 0.12 g and σ = 0.02 g. What is the z-score of a radish seed that weighs 0.093 g? If the contents of a seed packet weighs 30.0 g, approximately how many seeds are in it? Approximately how many seeds in the packet weigh between 0.08 g and 0.16 g.?
If all other values are held constant, what happens to the value of t when sample size increases ?
At any age, about 20% of American adults participate in fitness activities at least twice a week. However, these activities change as people get older, and occasionally participants cease to be older as they age. In a local survey of n = 100 adults over 40, a total of 15 people indicated that they participated in these activities at least twice a week. Does this data indicate that the percentage of participation for adults over 40 years of age is considerably less than the 20% figure? Find the p-value and use it to draw the appropriate conclusions.
Samuel Morse determined that the percentage of a's in the English language in the 1800s was 8%. A random sample of 600 letters from a current newspaper contained 60 a's. Using the 0.10 level of significance, test the hypothesis that the proportion of a's in this modern newspaper is 0.09.
