Integra learning systems is a private company that believes it can increase a child's IQ by giving them videos to watch, specific kinds of games to play, and by emphasizing a gluten free diet. Through these activities, the program insists that children are becoming smarter. They stress that smarter children leads to better learners, higher grades, and higher incomes as adults. A researcher wants to compare children that have been in this program to the general population. The researcher locates 10 such children with a mean IQ of 114. Are they different than the population? (For this example, IQ scores distribute normally with a mean of 100 and a SD of 15.) Z = X-μ ox (Write your answer in the box) B. We will use a two-tailed test. 0x = A. Wow, mean IQ of 114. These kids look smart. On the other hand, this could all be due to: 1. H₂: X = ø 2. H₁: X Ø # 3. Ho: μ = Ø 4. Ho: X = μ 5. H₁: Xu 6. Ho: X = μ Enter the number of the expression indicating the null hypothesis into this box: P √n 2 a 6 55

Let p denote the population proportion of all buttered toast that will land with the buttered side down when dropped. Identify the null and alternative hypotheses to test the claim that buttered toast will land with the buttered side down 50% of the time. Ho p = H₁p 0.5 0.5 (Type integers or decimals. Do not round.) Identify the test statistic. z = -1.81 (Round to two decimal places as needed.) Identify the P-value. P-value = 0.070 (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Fail to reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that buttered toast will land with the buttered side down 50% of the time. Write a conclusion that addresses the test that the toast will land with the buttered side down more than 50% of the time. The intent of the experiment was to test Ho: p = down more than 50% of the time. 0.5 and H₁: p > 0.5.…

Perform an independent-measures (samples) t-test in SPSS to determine if the starting salary (Variable "salary" "Starting Salary") of males is significantly higher than the starting salary of females. Use α = .01. p-value .0005 T-statistics 3.45 This is a one-tailed test because we are interested in whether the salary of one group is significantly greater than the salary of the other group Our assumption is this correct ? We reject the null because because .0005 is less than .01 and conclude male salary is greater than female salary ? or it is not greater ?
