For Numbers 11 to 13: A veterinarian hypothesize that a new formulation of shampoo is better than"kakawate", a popular control for getting rid of ticks on dogs which is found to be effective 75% of the time. Hewants to prove this claim, hence, a random sample of 50 infected dogs were obtained. If proven true, this newformulation will be released in the market.11. TRUE or FALSE: A type I error will be committed if the veterinarian concludes that new formulation waseffective on more than 75% of the infected dogs when in fact it is not.O TRUEO FALSE

Type 1 error: Type 1 error may be defined as the probability of reject Ho, when Ho is true.

An IQ test is designed so that the mean is 100 and the standard deviation is 16 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 90% confidence that the sample mean is within 4 IQ points of the true mean. Assume that o = 16 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. ...

A doctor wants to estimate the mean HDL cholesterol of all 20- to 29-year-old females. How many subjects are needed to estimate the mean HDL cholesterol within 4 points with 99% confidence assuming s=10.7 based on earlier studies? Suppose the doctor would be content with 95% confidence. How does the decrease in confidence affect the sample size required?

A farmer wants to know whether or not the sizes of Christmas trees differ between two separate fields on opposite sides of the farm (different elevation). In order to test this, he plants a number of trees in each field and measures them all after 2.5 years of growth. He then takes a random sample from each field and this is what he found: Group 1: Higher Elevation, N=25, Mean=3.3 ft, S=0.55 ft Group 2: Lower Elevation, N=23, Mean= 3.1, S=0.45 ft Please calculate the test statistic and pvalue. What can be concluded? Support your answer. Please calculate the 95% confidence interval Interpret the interval. What can be concluded? Support your answer.
The average age of managers in a particular industry is over 35 years old, and we wishe to prove this. The null hypothesis to conduct a statistical test on this theory would be: the population mean is ˃ 35, or the population mean is ≤ 35 or the population mean = 35 or the population mean is ≥ 35.
