The heights of fully grown trees of a specific species are normally distributed, with a mean of 68.5 feet and a standard deviation of 6.50 feet. Random samples of size 14 are drawn from the population. Use the central limit theorem to find the mean and standard error of the sampling distribution. Then sketch a graph of the sampling distribution. The mean of the sampling distribution is μx=enter your response here. The standard error of the sampling distribution is σx=enter your response here.

Suppose a random sample of size 54 is selected from a population with = 10. Find the value of the standard error of the mean in each of the following cases (use the finite population correction factor if appropriate). a. The population size is infinite (to 2 decimals). b. The population size is N = 50,000 (to 2 decimals). c. The population size is N = 5000 (to 2 decimals). Hint(s) Check My Work d. The population size is N = 500 (to 2 decimals).
Q1(10). Manatees are one creature found in coastal waterways. To study this creature, a random sample of 12 manatees were selected, the sample manatees were released before their weights (in pounds) were carefully recorded: 956, 1012, 954, 988, 973, 1048, 1075, 1064, 856, 1026, 1031, 1064. Assuming the underlying distribution of manatee weights is normal. 1(5). Find a 95% confidence interval for the true mean weight. 2(5). In a similar study 10 years ago, researchers concluded that the true mean weight of manatees was approximately 1000 pounds. Implement a hypothesis test to verify if there is any evidence to suggest the true mean weight is less than 1000 pounds now. Solve the hypothesis using P-value method. Let a = 0.05.
Suppose a simple random sample of size n equals 1000 is obtained from a population whose size is N equals 2 comma 000 comma 000 and whose population proportion with a specified characteristic is p equals 0.75. Complete parts (a) through (c) below.
In a previous year, 62% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 700 females aged 15 and older and finds that 428 are living alone. Is there sufficient evidence at the ax = 0.1 level of significance to conclude the proportion has changed? Because npo (1-Po) = 164.9 > 10, the sample size is (Round to one decimal place as needed.) Identify the null and alternative hypotheses for this test. Ho: p = 0.62 versus H₁: р # 0.62 (Type integers or decimals. Do not round.) Find the test statistic for this hypothesis test. Zo (Round to two decimal places as needed.) = less than 5% of the population size, and the sample is a random sample, all of the requirements for testing the hypothesis are satisfied.
