The type of information used in the scientific method that is based on observation or experimentation is called: empirical evidence
Empirical evidence is evidence obtained through observation or experimentation and it forms the basis of scientific knowledge. The scientific method requires the systematic collection of empirical evidence. This empirical evidence is then used to form testable hypotheses and theories.
First, a hypothesis is proposed and then experiments are conducted to test that hypothesis. Observations are recorded to determine if the hypothesis is supported or rejected. For example, if a scientist proposes that a specific substance causes a certain illness, they would collect empirical evidence to determine whether this hypothesis is true.
They would observe people that have been exposed to the substance and see if they experience the illness or not. They would also conduct experiments to see if the substance does in fact cause the illness.
The scientific method uses empirical evidence to form scientific knowledge and understanding. This empirical evidence is the basis for scientific theories and hypotheses. The evidence is collected through observation and experimentation, and it is used to form and test scientific knowledge.

Ten investigators from ten public universities surveyed 1181 ethiopian adults residing. In Addis ababa to gauge the demand for vegeterian meals in restaurents. The study , commissioned by the ethiopian ministry of health , polled independent random samples of 747 men and 434 women. Of those sampled , 376 men and 195 women said that they sometimes order a dish without meat , fish , or fowl when they eat out. Do the data from the survey provide sufficient evidence to conclude that percentage of A. A men who sometimes order veg is smaller than the percentage of Addis Ababa women who sometimes order veg?use 5% level of significance. Teste hypothesis properly
Using the hypothesis of the normal distribution that the percentage of Addis Ababa men at a 5% level of significance, the critical value for a one-tailed test is -1.645.
To test the hypothesis that the percentage of Addis Ababa men who sometimes order vegetarian dishes is smaller than the percentage of Addis Ababa women who sometimes order vegetarian dishes, we need to perform a two-sample proportion test at a 5% level of significance.
Let p1 be the true proportion of men who sometimes order vegetarian dishes, and p2 be the true proportion of women who sometimes order vegetarian dishes.
The null hypothesis is that the two proportions are equal, which can be written as:
H0: p1 = p2
The alternative hypothesis is that the proportion of men who sometimes order vegetarian dishes is smaller than the proportion of women who sometimes order vegetarian dishes, which can be written as:
Ha: p1 < p2
Using the given data, the sample proportions are:
p1 = 376/747 ≈ 0.503
p2 = 195/434 ≈ 0.449
The sample sizes are sufficiently large, and we can assume that the sampling distribution of the sample proportions is approximately normal.
The test statistic for the two-sample proportion test is calculated as:
z = (p1- p2) / √(p(1-p)(1/n1 + 1/n2))
where p is the pooled sample proportion, calculated as:
p = (x1 + x2) / (n1 + n2)
where x1 and x2 are the total numbers of successes in each sample, and n1 and n2 are the sample sizes.
Plugging in the values, we get:
p = (376 + 195) / (747 + 434) ≈ 0.474
z = (0.503 - 0.449) / √(0.474 × (1 - 0.474) × (1/747 + 1/434)) ≈ 1.892
At a 5% level of significance, the critical value for a one-tailed test is -1.645. Since the calculated test statistic is greater than the critical value, we reject the null hypothesis and conclude that there is sufficient evidence to support the alternative hypothesis that the percentage of Addis Ababa men who sometimes order vegetarian dishes is smaller than the percentage of Addis Ababa women who sometimes order vegetarian dishes.

Fein and Spencer (1997) conducted a study evaluating a job applicant whom the participants believed to be either Jewish or non-Jewish. The statement that is false about this study is: option A states "The study was conducted on a campus where negative stereotypes about Jewish women were pervasive".
The study found that participants were more likely to discriminate against Jewish applicants when they had previously been given negative feedback about their own abilities. This conclusion provides supporting evidence for one of the basic predictions of the social identity theory.
According to social identity theory, individuals prefer the in-group (the group to which they belong) and often show inter-group discrimination (favoring the in-group and discriminating against the out-group). In-group identification is associated with higher self-esteem, and individuals who were able to avoid discriminating against the Jewish applicant demonstrated the most significant boost to their self-esteem.
In contrast, participants who discriminated against the Jewish applicant demonstrated no change or even a decrease in self-esteem. In conclusion, Fein and Spencer (1997) conducted a study in which participants evaluated a job applicant whom they believed to be either Jewish or non-Jewish.

a drop in which hormone leads to initiation of the menstrual phase of the uterine cycle?
The drop in progesterone triggers the initiation of the menstrual phase of the uterine cycle. Progesterone is a steroid hormone produced by the corpus luteum, which is a hormone-secreting endocrine gland that forms from the follicle that released an ovum during ovulation.
Progesterone levels increase after ovulation, but they drop if an embryo does not implant in the uterus. The drop in progesterone causes the endometrium, which is the inner lining of the uterus, to break down, leading to menstruation.
Menstruation is the shedding of the endometrial lining, and it lasts for three to five days. This process is controlled by the hypothalamus, which produces the gonadotropin-releasing hormone. This hormone triggers the production of follicle-stimulating hormone and luteinizing hormone, which in turn control the ovarian cycle.
The decrease in progesterone at the end of the uterine cycle causes a cascade of events that leads to the shedding of the endometrium. This initiates the start of the menstrual phase and the beginning of a new menstrual cycle.
