Researchers from a certain country were interested in how characteristics of the spleen of residents in their tropical environment compare to those found elsewhere in the world. The researchers randomly sampled 93 males and 107 females in their country. The mean and standard deviation of the spleen lengths for the males were 10.8 cm and 0.9 cm, respectively, and those for the females were 10.2 cm and 0.7 cm, respectively. At the 5% significance level, do the data provide sufficient evidence to conclude that a difference exists in the mean spleen lengths of males and females in the country?

Suppose the final exam scores in Statistics and Probability of all SHS students at Laguna State Polytechnic University follow the normal distribution with population mean of 32 and standard deviation of 7. Further, the teacher assumes that the true mean is 32. A random sample of 32 SHS students were selected and their final exam scores were gathered. The computed sample mean is 29. Is there enough evidence to say that the teacher's claim of the true mean is true? Use 0.05 level of significance. Conduct the five steps of hypothesis.
Suppose a English lecturer believes that there is no significant difference between the average class scores of his two classes, mekar and mawar on final exam. The average and standard deviation for class mekar of 35 students were 75.86 and 16.91.The average and standard deviation for calss mawar of 37 students were 75.41 and 19.73.Using these results, test the claims at 5% level of significance.
A study was designed to investigate the effects of two variables - (1) a studentʹs level of mathematical anxiety (2) teaching method - on a studentʹs achievement in a mathematics course. Students who had a low level of mathematical anxiety were taught using the traditional expository method. These students obtained a mean score of 290 with a standard deviation of 50 on a standardized test. Assuming no information concerning the shape of the distribution is known, what percentage of the students scored between 190 and 390? Group of answer choices At least 68% At least 95% At least 75% At least 88.9%
A new small business wants to know if its current radio advertising is effective. The owners decide to look at the mean number of customers who make a purchase in the store on days immediately following days when the radio ads are played as compared to the mean for those days following days when no radio advertisements are played. They found that for 10 days following no advertisements, the mean was 18.3 purchasing customers with a standard deviation of 1.8 customers. On 7 days following advertising, the mean was 19.4 purchasing customers with a standard deviation of 1.6 customers. Test the claim, at the 0.02 level, that the mean number of customers who make a purchase in the store is lower for days following no advertising compared to days following advertising. Assume that both populations are approximately normal and that the population variances are equal. Let days following no advertisements be Population 1 and let days following advertising be Population 2. Step 3 of 3: Draw a…
Suppose two proposed computer mouse designs were compared by recording wrist extension in degrees for 23 people who each used both mouse types. The difference in wrist extension was computed by subtracting extension for mouse type B from the wrist extension for mouse type A for each student. The mean difference was reported to be 8.81 degrees. Assume that it is reasonable to regard this sample of 23 people as representative of the population of computer users. (a) Suppose that the standard deviation of the differences was 10 degrees. Is there convincing evidence that the mean wrist extension for mouse type A is greater than for mouse type B? Use a 0.05 significance level. (Use a statistical computer package to calculate the P-value. Use μd = μA − μB. Round your test statistic to two decimal places, your df down to the nearest whole number, and your P-value to three decimal places.) t= df = P-value = State your conclusion. Fail to reject H0. We have convincing evidence that the mean…
An instructor of statistics believes that the mean score of students on the first statistics test is 65 out of 100 marks. He randomly samples 10 statistics student scores and obtains the average scores as 63 with a standard deviation of 5.01. He performs a hypothesis test to know whether the mean score of students is varied from 65 by using a 5% level of significance.

Suppose that you want to test the hypothesis that mothers with low socioeconomic status (SES) deliver babies whose birthweights are lower than “normal” at the 5% significance level. To test this hypothesis, you want to conduct a study in which you collect data from full-term live-born deliveries from various maternity wards of hospitals in low SES areas. It is assumed that the standard deviation of birthweights is 24 oz. A national survey has shown that “normal” birthweight is 120 oz. You want to consider being able to detect differences of 5 oz, 10 oz, or 15 oz below normal birthweight. You decide to construct a power curve for each one of these differences where you look at power as a function of sample size. These three power curves are provided below. 1. Match each curve with its correct label regarding birthweight differences (5, 10, or 15 oz). 2. What is the standardized effect size if the difference of interest is 10 oz below normal birthweight?

A researcher is interested in examining the effect of emotions on those that are convicted of a crime while under the age of 15. She decides to compare the empathy quotient (EQ) scores of those convicted of violent crimes to those convicted of non-violent crimes. A random sample of 35 violent offenders had a mean score of 33.5 and a standard deviation of 3.2, and another sample of 46 non-violent offenders had a mean of 37 and a standard deviation of 3.8. Also, suppose that equal variance cannot be assumed, but the populations are normal. If a higher EQ score indicated increased empathy, construct a 95% confidence interval for the difference in means. What is the critical value? What is the lower bound of the confidence interval? What can she conclude about the difference in empathy between the two groups?
