**Hypothesis Testing for Entering Students' IQs**A college professor claims that the entering students this year seem to be smarter than those from previous years. Historically, the mean IQ for entering students has been 110. To analyze this claim, we will conduct a hypothesis test using a sample of this year's entering students.### Hypotheses- **Null Hypothesis (\(H_0\))**: The mean IQ of this year's entering students is equal to 110.- **Alternative Hypothesis (\(H_1\))**: The mean IQ of this year's entering students is greater than 110.### Hypothesis Testing Process1. **State the Hypotheses**: Define \(H_0\) and \(H_1\) as above.2. **Collect Data**: Gather a sample of IQ scores from this year’s entering students.3. **Analyze the Data**: Conduct statistical tests (e.g., t-test) to compare the sample mean to 110.4. **Draw Conclusions**: Determine if the data provides enough evidence to support the professor's claim.This approach will help evaluate whether the observed difference in IQ scores is statistically significant or due to random chance.

A sample is selected from a population with a mean of m = 30 and a treatment is administered to the sample. If the treatment is expected to increase scores and a t statistic is used for a one-tailed hypothesis test, then which of the following is the correct null hypothesis?
In a recent Super Bowl, a TV network predicted that 52 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl.

You take 115 random samples from a population of trees for which the mean height in feet is μ=72μ=72 (but you do not know this), and use each set of data to do a hypothesis test at a 5% level of significance to determine if the population mean is not 72. So the hypotheses are:Ho:μ=72Ho:μ=72Ha:μ≠72Ha:μ≠72In how many of the 115 hypothesis tests would you expect to reject Ho and conclude that the population mean is not 72? Do not round your answer.
Suppose you have a friend that thinks at least a quarter (25% or 0.25) of all US adults believe in ghosts. Thus, the null hypothesis would be, HO: p = 0.25 Suppose a telephone survey of 1000 randomly selected US adults found that 0.31 or 31% of them say they believe in ghosts. If the null hypothesis is true, the uncertainty or Standard Error in this sample proportion = 0.014 Based on this information, what is the value for the Z-statistic in this hypothesis test? (Round your answer to two decimal places.) Answer:
Brett is a huge sports fan. He hypothesized half of sports fans liked football the best, 25% liked baseball the best, 15% liked basketball the best, and 5% liked hockey the best, and the rest liked some other sport the best. He surveyed 500 sports fans and asked what sport they liked the best. Which of the following is the way to calculate the number of these 500 sports fans expected to say that basketball is their favorite sport if the null hypothesis is true? ...... Choose the correct answer below. A. (500)(0.20) B. 500 - (500)(0.20) 500 C. 0.15 D. (500)(0.15)

A professor notices that more and more students are using their laptop computers in class to take notes. He wonders if this may improve academic success. To test this, the professor records the number of times each student uses his or her laptop during a class for one semester (Laptop) and the final grade in the class out of 100 points (Grade). The professor wants to conduct a hypothesis test to test whether or not there is a significant relationship between Laptop and Grade at the .05 level of significance.
